Following suit after its European counterpart's announcements, Sony Computer Entertainment America (SCEA) recently revealed its own line up of downloadable goodies on the PlayStation Store. This week's PlayStation 3 Store updates include a lot of added game content for Hot Shots Golf, Karaoke Revolution Presents: American Idol Encore, Rocketmen, as well as another regular update for Rock Band.

In addition to this, gamers can try out the new Dragonball Z: Burst Limit demo for free. If yellow haired, Super Saiyans aren't your style, you can also check out the Overlord Raising Hell demo for some twisted action RPG action.

On the PC Store side of things, SCEA is offering a sneak peek into the upcoming Ratchet & Clank spin-off with Secret Agent Clank for the PlayStation Portable. As always, a host of free downloadable themes, videos and wallpapers are also available for those on the lookout for a little eye candy.
