Okay, so, this is not true, but really, that's a lot of games only by three publishers and developers, perhaps in response to the generally poor international response to last year's TGS. (Then again, what were the people complain about?) They were in Japan! (I was not!)

Anyway, according to Andriasang, and various other websites, the TGS 2011 lineup for Sony, Capcom, and Sega are as follows:
