It's far too long. I'll be like... 17 by then! Blergh...
Oh, there's another Disney movie coming out, sometime in 2013 I'm pretty sure, entitled Frozen (The Ice Queen was it's previous title). I think I've already discussed that one somewhere else. I'll post some concept art. It looks pretty amazing.
Now there's some very old concept art, I'm not sure how old the above one is, that are from prior to 2003. It looks as though the entire concept of the film was being flip-flopped and changed.
There's more, too many pictures to post so here's the Tumblr page for Frozen concept art:
