It will be just like old school poverty days lol sorta
I have 5 screen possible setup which would keep everyone playing something at least. Sounds like 3 PS3s so far Anti, Rich and Me and I have 1 copy of most fighters, sold Mahvel and AE.
I have a 360 but only thing worth playing on it is Mushihime sama. Or i can bust out S.Saturn for some galaxy fight LOL
edit I have about 5ish sony sticks assembled atm so dont forget your sticks!
