And just looking a little closer at those pictures, I just remembered something: Epic and someone else (may have been MS) had huge areas like that last year.
They are pretty much big closed off cubicle like places where they just do a lot of interviews and meetings. Nothing really new. I bet if you get the complete floorplan of all the whole area (because I know that isn't it after looking closer) Epic and MS Game Studios will have a smaller normal booth.
-edit-
Is anyone here going to GDC? I'll more than likely be there if so.
