I disagree that Halo is the flagship multiplayer game of 360. Halo shares that title with GOW 2.
The different classes for multiplayer sounds very intriguing and the rumblings about how great this game is continue throughout the internet.. I'm gonna be really dissapointed if this game bombs and it's just the Sony marketing machine at work here.
It will be better than Resistance 2 though, which isn't hard to do. The game looks awesome, the only thing that bothered me a little was the wimpy effects of the flame thrower. Then again, after you used in on someone, the effects really shined seeing someone run around on fire.
Oh, and this game better be in true 1080i(p) right out of the box or I'm gonna bo absolutely nuts.
