Although they may not have revealed this in the E for All demos, one way of checking would be cycling through the costume choices. obviously if there are 8 different costumes for each character, you will be able to play 8 player multiplayer. BUT, i do not think that just because there are 4 costumes you CAN'T do 8 players, because maybe they are hiding the others or something.
Did anyone go to e for all and check on this?
