I don't know anyone who's purchased the system and I am dying to play some multiplayer. Anyone else interested in this might want to chime in and just give what city they live in. Then maybe people can arrange a way to be in some sort of proximity with each other to play.
<- in NYC
MUST PLAY GAME!!
