Sorry I jumped off so suddenly last night. I was summoned by the wife rather urgently. The 360 sometimes comes between us, and she had had enough of that for the night.
Anyway, I think the multiplayer is OK. The vehicles are pretty fun. My major complaints are (1) I do not feel a sense of "weight" from my character when I'm moving around, etc...Gears of War does this wonderfully; perhaps it's the 3rd person perspective? (2) I don't really "feel" it when I make a kill, as I do in GOW. I get no real sense of accomplishment (or defeat, as is the case more often than not

) once a round is complete.
