Xbox 360 Round-up - COD4 patch, Marketplace goodies

The big news for Xbox 360 fans this week is the Call of Duty 4 patch, which adds more kill cams, better sniper and ACOG scope accuracy, more spawn locations, improved network performance, host migration (so the party continues after the host drops), quick mute and expanded spectator cam options. Plug in the game and accept the patch, or you won't be allowed online anymore.
