theres no official date to wen its gonna be released according to gamefaqs, so for now guess u gotta spend $2 playing it at ur arcades. Tekken 6 seems to be a common thing from where i live we got like around 10 or so in the arcade
Tekken 6 is released not long ago, I've played it and you will really regret on buying it lots of moves were disabled already and especially delay will really occur alot!
