I added some information about the 3D Conversion on the movie to the post just a few above this one:

viewtopic.php?f=5&t=1159&p=90343#p90343

Turns out the conversion for the movie was done by Prime Focus World of "Clash of the Titans" conversion fame (compared with the trailer which was converted by a company called Stereo Pictures)

What do you know about Greg Spalenka?

The new Narnia film "Voyage of the Dawn Treader" hits the theaters this December. Greg contributed significant amounts of artwork to the visual development of the film, working intimately with director Michael Apted. ... This evening, just as we have arrived from a whirlwind trip to SF we will be attending a special preview on the lot in Century City. In the meantime from what we can see of the trailer much of Greg's work was used. Unlike The Golden Compass film where his work was cut when the producers decided to shift the ending to a second film the new Narnia film is rich with his vision.

Greg had a bunch of artwork he posted a year and a half ago on his website (same stuff that recently resurfaced on DanielJ's blog... which he probably shouldn't have posted ). It was picked up by NarniaFans and both fansites did stories on it. I believe poor Greg got in trouble because we were contacted by him a short time later asking if we would please remove the images from our sites and he took his artwork down too. You can see the old story here.

I'm hoping that we can repost it after the movie comes out.

Thanks, fantasia.

This stuff is over my head, but I think rumors are being confirmed, or at least VFX blanks are being filled in...
