Starting in 2015, the output of both Pixar and Disney will double. Disney Animation will release TWO films every other year, while Pixar will do 2 annually.
In fact, Dreamworks, are already doing that (Turbo, The Croods). And other's will follow suit.
Since in a few years, animated films will saturate the market with more title, what does that mean for the noms for the Oscars? There will be casualties.
I can't see the Oscars wanting to nominate 2 Pixar films and 2 Disney films in one year. That would be a total monopoly and would destroy the chances of other studios of getting a pice of the action, like Laika or Studio Ghibli.
