I have not the words to do this game justice.  I'm still in shock over how the new HD trailer looks five times better than the playable demo we already have to samlpe.  DAMN this game is going to be phenominal!  This along with Mass Effect and Bioshock have me on pins and friggin' needles!  Damn, I'm so broke next year....DAY ONE PURCHASE!!  :D

I have yet to see proof that this game is more than 8-player maximum.  I especially like how the players are generally arranged as if they are fightings players that are off screen when all of them are one screen! 

Until I see otherwise, I'm assuming it's 8-player (one of the trailers/gameplay footage) showed the results screen with the 8 players on it...
