It's been well over a decade since the last installment in the Tekken Tag Tournament series (if you can call two entries a series,) but Namco Bandai have now announced when TTT2 will be migrating out of Japanese arcades and into home consoles.
The date they're currently setting is September 20, 2012. They've also announced some special edition bonuses, though the package is just for European territories so far. Nevertheless, the "We Are Tekken" special edition will include a copy of the game in a nice metal case, a behind-the-scenes DVD, a 200-page hardcover art book, and a soundtrack remix album.
Beyond that, there are also some pre-order bonuses depending on which retailer you pre-order from (in Europe.) Ordering from ShopTo will net you Michelle Chang and Angel as playable fighters, while ordering from Zaavi will get you Kunimitsu and Ancient Orge.
