A large number of demos have hit the US and European PlayStation Stores this week, with samples of Katamari Forever, LittleBigPlanet, Fat Princess and (gasp!) Fifa 10 (European only at the moment) show up on the service.

The PAX 2009 and Freezepop track lists are also available to buy and download for Rock Band, while a host of other new tracks have been added to the game, as well as Guitar Hero 5.

The usual assortment of game add-on content, interesting videos, wallpapers and themes (normal and dynamic) make this week’s PlayStation Store update much more interesting than weeks past.

Check out the full list of content available now on both the European and US PlayStation Stores this week to see if anything catches your fancy:
