100 million PS4 lifetime is impossible...

Yeah, I expect 100 million as the minimum for PS4 sales, unless Microsoft manages to drop a couple megaton bombs for the XBOne.

I don't expect Japan to be a big market for PS4, though. I expect it to keep momentum, Vita-style, if you know what I mean by it. (From what I know, this year has been the only year where Vita at least kept up with 3DS, and this is its third year.)
