Quoted from markmon:
I don't see why they need to redo all the code, call outs, or DMD animations of they change the art package. The art package can be comic book style with the same voice sounds we have. Someone has to produce the callouts. No reason it can't be the voice actors used in the movies. Also the DMD animations apply for the same reason. I don't see them doing a ton of coding or porting the game to spike.
If they're going to license the movie assets for audio and dmd - then there's not much point in redoing the art package. The whole rumor is very odd.
