Yes, the Call of Duty 4: Modern Warfare PlayStation 3 Variety Map Pack arrived for both North America and Europe as promised. But if European/PAL PlayStation Store gamers want to find more fuel for the difference-in-PS-Store-service argument, they should just look at the Echochrome demo which only the North American community can get their hands on this week.

This week features a boatload of updates for the US PlayStation Store from add-on game contents (Rock Band, Guitar Hero III: Legends of Rock), demos (Iron Man), videos and themes. Sony PlayStation Portable gamers get their fix too this week with an update on the PlayStation Store for PC. Here are this week's complete offerings:
