I know part of the reason I'm disappointed is that on the official movie website, they posted a few images in the gallery back in June. The images posted were pretty decent 3D computer generated shots of the dragons and draconians. The background images also seemed to be decent CG shots. They only had concept artwork of the main characters, so I had an expectation that it would be a similar style for them as well.
I looked at the website again today, they have not updated any of the images in the gallery, so nobody had anything more to go by (although now looking closer at Paladine in one image, I can see he was drawn in the 2D animation style).
Also, it appears that YouTube is the official distribution method for the "rough cut" trailer, since that is what they have on the official website. Would have been nice if they had a better quality download available there, but maybe we are better off not having it and hoping it will look better in higher res...
