CnC3 Muliplayer

I've played the demo on xbl and it is great btw, but in multiplayer there are only 4 boxes for players. In the PC version depending on the map can have 8 people. Does anyone know if the 360 version can only have 4 people or if it is just the demo and/or gametype?

I have a question about the multiplayer too. I have read that the Xbox 360's multiplayer will have four exclusive multiplayer game types, which makes a nice addition to a great game, but I haven't heard anything about the standard multiplayer game types. If it isn't possible to play standard multiplayer matches on the Xbox 360 version then I'm just going to purchase this game for PC. Are these four exclusive game types the ONLY game types available for Xbox 360 or are they exclusive additions?
