Not quite. Like Winnie the Pooh and Mulan, this film has not been officially announced by Disney. All three of these film's source rumors originate from different new websites. I'm sure they're all well sourced. (and some of them even look as though Disney is testing the waters. Am I the only one who finds it strange all thse projects have been announced back to back to back?) My point is I'm still waiting for the Matterhorn Movie coming out... Projects this early can die, and until Disney (from their PR department) announces they're moving forward we need to remain calm.
Once they do that, we can then freak out...
