And in yet another example of the Xbox team not knowing what they're actually meant to do, another release this week - FunTown Mahjong. Well, maybe. You see, FunTown Mahjong hasn't actually been announced officially, only leaked via Xbox360Achievements.org and various other websites. Major Nelson have claimed that FunTown Mahjong has been released, but it has not got an Xbox.com splash page, hasn't got a marketplace page, and 2 hours after claiming to now be available, is not.

Congratulations Microsost, you've allowed another XBLA game to go (supposedly) released unannounced, and now likely to sell far fewer copies than it probably could otherwise.
