According to C&VG, LittleBigPlanet won’t be out until the Autumn:

Sony has confirmed with us this morning that LittleBigPlanet will be out in September.

An autumn release date for the quirky PS3 game was hinted at yesterday, when producer Kyle Shubel spoke about the 2008 timeline for the title in a demonstration at CES in Las Vegas.

A LittleBigPlanet demo was expected toward the end of 2007 but failed to materialise. A rep from Sony UK had no further news on a release date for the demo at this time.
