Source: Tekken producer Harada: No DLC characters for usCapcom's been explaining itself over the on-disc DLC that came with Street Fighter x Tekken, but Tekken series producer Katsuhiro Harada said there will be no such problem with his side of the franchise. Because, you see, he told Edge that no Tekken game will ever have DLC characters at all.
Mr. Harada, I do believe you just sold another copy of Tekken x Street Fighter.
And possibly a copy of Tekken Tag Tournament 2 as well.
