I will certainly miss the Walden cast and we may see the old Pevensie actors play the adult versions though it still seems a little unlikely, but others (ie. Ben Barnes as Caspian X and Will Poulter as Eustace) may be gone forever.

The cast of the Walden films was very good and I definitely will miss them. I was hoping that Georgie Henley would able to return in another role since she might not be able to play Lucy except in an adult role, e.g. The Horse and His Boy and The Last Battle.  It would be years before those movies could be made, but there is hope of some of the cast returning as other characters.  They did a good job in choosing the actors in the Walden movies.  Ben Barnes was too old for Prince Caspian in the second film, although he was quite good and the correct age in the Dawn Treader film.  I thought the casting was much better than the story adaptation in the second and third Walden films.

Yeah. Though some of the cast from the Walden might be given some kind of a role in the new franchise. In a recent news, Will Poulter, who played Eustace, said that he would be down for another role in Narnia. So he might end up being cast as Lord Peridan in HHB or King Tirian in LB. 

It will sure get interesting about the new franchise.

I am also very curious to see what role he gets!   A relief I have is the very likely chance that Netflix's VDT will be green mist-less!   Though I am still worried unnecessary romance may be implemented (Like the whole Suspian thing)

Ooh, yes! That is a relief! There will be no Green Mist! I still like to pretend it never happened!

Not only that, but VDT wouldn’t be turned into “saving the world” plot. A big battle scene or even just a small one doesn’t convert very well with VDT. There’s so much you can do with a battle scene in LWW, PC, HHB, and LB without departing so far from the books (not as epic as the Walden and also not as cheesy as the BBC). Though it doesn’t convert as well in VDT, SC, and MN.

Yeah. I don't expect it, but I am kind of worried about that.   I honestly can't see a shipping of Eustace and Jill happening in SC, but I can almost see a love triangle enforced with Tirian, Eustace and Jill in the LB. I know there are fans out there that like to ship Tirian and Jill, but I'm sorry, I don't ship them at all.

Romance isn't a big part of Narnia. As I've said before, I am generally fine with a boy and girl being close, but they don't have to fall in love. Media will often say that if a boy and girl are that close, they have to be in love. Well, real life isn't like that, if you think about it.

I think Greta Gerwig fully realizes that the Green Mist did not work for the Dawn Treader movie and that using something like that would be a big mistake. But if she makes another film on that book will she invent another villain that was not in the book?  There will probably be many liberties taken with the story anyway. But adding villains would not be a good thing if Lewis didn’t intend to have them in the book.

Another loss I have is we won't be seeing Walden's Dawn Treader Design! I loved the design despite the film's flaws. I am unsure if Netflix could beat Walden at it.

@queencrunchytheweeb 

I also liked the design of the ship in the Walden movie, but I wish it was a complete ship.  If you watch the bonus features on the DVD or Blu-ray you will notice that the ship had no bottom. Although this is not visible in the film itself, knowing that the ship is not a complete vessel makes the Dawn Treader seem more artificial than it was in the book.  I guess that they have made other props this way for other movies, but I think it would have been more realistic to have a complete ship.

@narnian78 Most movies have a certain amount of artificiality, and we usually just accept that there were tricks, CGI, greenscreen etc. It's like going to the theatre and accepting 'suspension of disbelief' to enjoy the play (eg flat painted scenery is 'trees' or 'a brick wall'.)
On Narniaweb, we watched the production updates and lots of photos came through from locals who had been able to see the ship set it in its various stages. This didn't stop me enjoying seeing the ship on screen though.

I actually give credit to the filmmakers of the Walden for designing the Dawn Treader! They did such a great job on it! It will most likely look different in the new adaptation.

I agree with @narnian78 that the new adaptations of Narnia will be given some kind of creative license. Greta Gerwig will certainly have a creative vision of Narnia.

With the BBC Narnia the Dawn Treader ship was a boat covered with polystyrene. I guess doing that was necessary because the film had a much lower budget than the Walden films. It was a little disappointing to find out, and I actually was more pleased with the Walden design. A complete ship would have been better and cost more money, but what they had was beautiful.  I think that some people were overly critical of the Walden film, although it did have some flaws in the story adaptation.  It was on the whole very enjoyable, and I was happy that I bought it on Blu-ray along with the other two movies. 

Plus, the landscape of Narnia looks really nice in the Walden. Though I’ll admit that it does come to a point where it’s too distracting at times. 

It will also be a relief that Greta Gerwig won’t keep bringing back the White Witch. I was actually kind of surprised when I saw her in the trailer for Walden’s VDT, and was like, “Is she going to be in all seven movies?” I kind of saw what they were trying to do with her in PC. Then they squeezed her into VDT. History may have a way to repeat itself, and certainly wouldn’t want to keep bringing back the White Witch to be one of them. I don’t think she’ll be in all seven, which is a relief. 

@Narnian78: A complete ship would have been better and cost more money, but what they had was beautiful.

Yes, the set for the Dawn Treader was really good to see. I've visited it, when it was at Coomera, on Queensland's Gold Coast Movie World Theme Park, at the end of 2010. That ship setting could be mounted on some sort of engineering gizmo, permanently set up on Warner Brother's filming lot, to enable scenes to be filmed on the boat, itself, allowing filming to take place regardless of the scenery. I've walked on its deck, & I've a photo of my husband & myself, beside the dragon head prow of the ship. There was a real back for the stern, with those casement windows. But the door to below decks could not be opened, because I can remember trying to do so. 

The main advantage of this mechanism is that it could be more cheaply & quickly disassembled & moved by semi-trailer or be shipped, to wherever it was needed. Yes, the Whitsundays where some of the filming was done, is very lovely scenery. They chose that volcanic White Island, (Whakaari) off the coast of New Zealand, to do some of the filming, but though in 2010, it was okay to film there, a decade later, in 2020, the volcano exploded, and members of a touring group were killed, when not all were evacuated in time. Chances are, the filming for the Voyage of the Dawn Treader, will be considered a unique occasion, & nobody else might take the risk of ever filming there again. 

@waggawerewolf27 Just a correction about White Island:

There was no actual filming there. Cast were not on the island, it was merely used for background, still shots.  This was done from a boat, I believe, not from photographers going onto the island.

[no need for me to comment about how unwise it was to use a live volcano as a tourist attraction]
