Not sure if Joystiq is behind due to Christmas, my Google Reader is being slow, or they're moving their new release news to Tuesdays.
No retail releases this week. If anything's coming for XBLA, or if there are any demos, nothing's been announced yet. And there's no Guitar Hero DLC, and I haven't heard if there will be any Lips DLC.
Gold Member Deal of the Week (Monday) - The Maw (400 points)
Rock Band DLC (Tuesday; 160 points each or 440 for the McCartney pack or 880 for the Country pack) - Alan Jackson: Good Time - Cross Canadian Ragweed: Cry Lonely - Jason Aldean: She's Country - Keith Urban: I Told You So - Kenny Rogers: The Gambler (HELL. YES.) - Martina McBride: This One's For the Girls - Shania Twain: Any Man of Mine - Paul McCartney: Band on the Run (live) - Paul McCartney: Jet (live) - Paul McCartney: Sing the Changes (live)
