I don't see how CGI can get any better than it already is.
Also, I'm annoyed with all those people who believe we should revert to 2D traditional animation. They don't have as much backup as they think they do, and they're fighting a battle they can't win. Whenever a 2D traditionally animated movie and a 3D computer animated movie come out in the same year, the 3D computer animated movie always makes more money.
