The 3d is nice - there is depth and at times pop out (for pop out fans). Nothing aggressive, but looks completely natural. So for those who want expanded depth, you're going to be disappointed.
Unfortunately, I think because it's Disney, there may not be a 3d release at all, even from imports...
Very enjoyable movie though. If you are a geek, you must get this on blu-Ray or even 4k because there are a lot of details you'd want to freeze frame and inspect.
If it wasn't for the fact that the movie is only a regular theatre showing (even with 3d) I'd probably see it again.
