Tekken Tag Tournament 2 is currently only announced for the Japanese arcade release in summer 2011, but it is likely that it will find its way to other territories and platforms like previous games in the franchise.

SDTekken reports that it will use the same five-button control-scheme as the original Tekken Tag Tournament. I'm excited about this title as Tekken Tag Tournament was the last Tekken game I seriously played back when I was still frequenting arcades as a youth. It looks like further information, including the character roster will be coming at a later date, but a trailer has been released.
