The guys over at Siliconera caught up with Tekken producer Katsuhiro Harada during Comic-Con and he gave them a few clues as to who the next set of characters are in Tekken Tag Tournament 2. These hints are quite vague and don't really give anything away, but I suppose your guess is as good as mine. Who do you think they are?
Hint 1: "One is a character a lot of people have been asking for his return. So, maybe they won’t be surprised, but a lot of people will be happy to hear about this."
Hint 2: "Maybe, it’s not quite a new character, but it’s one people will be very surprised at. This character is one that they wouldn’t have discovered."
