Unless Disney stops having people with MBA's attempt to tell the story then it doesn't matter what format the movies will be in.
I just hope that the market gets flooded with all these CG movies that people get sick of them realllllly fast. And the cream stays at the top while the crap falls by the wayside. I liked it when the CG movies were a novelty, so when it was a good film, it made it that much more special.
