Against it. I'm probably going to end up buying it anyway, but seeing as all of Treyarch's MP games were incredibly unbalanced (CoD3: Team Picking, CoD5: MP40, BO: Famas), I'm definitely not going to get into the multiplayer as much as I did with previous generations. The campaign looks interesting, and the campaigns have been Treyarch's strong point. I'll probably like the campaign; multiplayer not so much. It's a shame most people only buy Call of Duty for the rage-inducing multiplayer.
On a side note, after seeing the trailer again, the graphics seem way over-contrasted and over exaggerated. I just hope that's only in the trailer's case though.
