Some things you can't do with CGI, but what I really wish is for 2D animation to return to America. (It still lives in at least Japan and Argentina)
As impressive as the CGI-imaging in films like Advent Children were, you really can't replicate what can be drawn by hand. Sure, there are some really crappy animations like Shin Chan (Which HAD to have been done with markers and crayons), but a hand-drawn character has as much character behind them as an uber-realistic CGI-model.
Heck, look at what 2D-animation can do...Sephiroth looks manlier in that Final Fantasy 7 Anime than he does in Advent Children.
