American PSN update for December 11th

Nothing too exciting for Americans, this week. Today's update consists of four videos, and that's it. No playable content, no themes or wallpapers, just some videos. Hilariously, three of the four trailers are for content only accessible via a PS3, so those of you who own only a PSP have very little to download this week. Here's the list:

• Resistance 2 "Accolades" trailer

• X'Amd Lost Memories "Exclusive Interviews" video

• X'Amd Lost Memories "Release Announcement" video

• Brain Challenge video
