The guy is counting in the wrong way...
Booths: Sony (3), Microsoft (2) and Nintendo (3)
Meeting rooms: Sony(5)
One of MS booths is close to two times the biggest booth from Sony and Nintendo... I can say the spaces are even... Meeting rooms are for official business or press only.

I hate it when people do that. Video game journalism is seriously getting to the point where it's all garbage and you can't trust anyone to report the news properly. Even the big ones are getting their reports very wrong.
Oh, and the exclusive you guys are thinking of is Without Memory. Which is fudgy funny considering you can't remember the name of it.
