Why the smurf have movie execs decided that 3-D is a good thing?

From Variety.com:

Paramount's getting the blues, acquiring film rights to vintage cartoon characters the Smurfs and setting up development of a 3-D CGI feature with producer Jordan Kerner and Nickelodeon Movies.

Producers have conceived the project as a trilogy and are aiming to release the first film in 2008 to coincide with the 50th anniversary of the Smurfs.
