AAK on the Neogaf forums has confirmed at least a roster of 43 characters after extensive testing and reports from the Tekken Tag Tournament 2 (TTT2) arcades locations at Namco Land Kawasaki and Namco Land Umeda. The arcade banapass card costs 300 yen, but it stores all of the player's data for stats and competitions. Also of interest is that the Deluxe cabinet apparently costs 4,180,000 yen, which is upwards of $50,000US (no wonder our arcades can't keep up?). You can examine the thread at Neogaf further for more information, though much of it is so steeped in fighting game terminology that it confuses us and the English language.
