AWN has a great article talking about how 3D Animation is now not simply an afterthought, but is quickly becoming and an integral part of the movie-making process.

More than 50 years after its debut, 3-D movies are an idea whose time has finally come — and nowhere is that more apparent than in animation. It’s animation — CG, in particular — that to date has made the best use of 3-D and is in many ways best suited to the technique with its 3D virtual space.

Dreamworks in particular has declared that all future animated films will be entirely in 3D.  Hopefully some other studios will start to do similar.
