It"s an exciting week for PlayStation 3 owners, with a whole slate of cool new content to be downloaded from the PlayStation Store today. First up is the PSN-exclusive demo of Marvel vs. Capcom 2. If this week"s Game Night wasn"t enough MVSC2 action for you, PS3 owners can try out the game for themselves ahead of the game"s release this summer. PSP owners also get a demo this week in Patapon 2.

Those willing to part with a few dollars for some downloadable content will find plenty more of interest. The Killzone 2 Steel & Titanium map pack ($6) adds two new maps to the game"s multiplayer mode; Burnout Paradise adds the long-awaited Cops and Robbers mode ($10); Little Big Planet grabs some new stickers and costumes in the Egyptian mini-pack ($3); Disgaea 3 gets a variety of content, including new characters ($1-2 each or $4 for a bundle) and a new survival mode ($4); Need for Speed: Undercover gets a free challenge series expansion and a boss car bundle ($5), Guitar Hero World Tour adds three new tracks from Nirvana ($2 each, or $5.49 for a bundle); Rock Band gets an entire album of Jane"s Addiction ($2 each, or $16 for a bundle); and PSP gets some rare downloadable content for Prinny Can I Really Be The Hero with the addition of a new stage and boss ($4).

Aside from that, the only noteworthy addition is an announcement trailer for Battlefield 1943 and some themes for PS3 and PSP.
