I suggest that it will be like [[wikipedia:Who Framed Roger Rabbit
 * Who Framed Roger Rabbit]], which has the 2D characters interacting with the live-action actors, or The SpongeBob SquarePants Movie, with the majority of the film being animated like the show, with a certain scene featuring the 2D characters in a live-action environment.

I doubt that the film will be CGI/live-action like Yogi Bear or Alvin and the Chipmunks, seeing as Disney has never done those types of movies before (Warner Bros. usually does). As well, only classic shows or cartoons are given that treatment, while P&F is notably recent. Therefore, I doubt it will be this type and more of the former.
