While Pixar may have "planned for 3D" from the beginning, I would bet cold hard cash that the director's preferred version is 2D and 3D is just what has to be done for the bottom line folks.

You see, the problem with 3D is that for the addition of the 3D effect you lose SOOO much of the nuance of color and texture as it's masked by the polarizing lenses.

As another voice on the matter, Roger Ebert has a great post on this very subject. http://blogs.suntimes.com/ebert/2009/05/up_up_and_away_in_my...
