^The sound? Yeah. It was there when I saw it in imax 3D. I can't speak on the animation differences, though; they're too minuscule for me to recall unprompted. This review seems to imply that most were corrected but that a few remain.

Update: I received the discs today and I'm thinking about how to distribute them as we speak. I'll probably up them in iso format, wherever they go. Note that they're both single-layer DVDs.

I wish I could buy the 3D disc without having to buy the Diamond Edition in that set; the colors are so much better, but I don't know if my PS3 will downconvert it to 2D...
