no four-player co-op ?

gears of war 2 (one game i'm totally looking forward to).it will be out this november.everyone like the sequel's better graphics , destructible environments , soft body physics , better water effects , crowd feature (which means having a lot of character models appear on the screen).it has new weapons , enemies , locations , characters , bla bla bla.and it's xbox 360 exclusive.but what we all want most is four-player co-op.during the old times , there's only 2 player co-op in most video games.but halo 3(which is also a x360 exclusive) proved that wrong , by giving 4 people to play together.so now a lot of 360 owners are wondering whether gears of war 2 will do the same.and the only thing we could get was a simple " we don't know yet ".so stay tuned.
