A taste of the conquest pacing was had in the park. Unless the LAV operator knew what he was doing (and took B immediately, then backtracked to A to cover it as well) it was a battle from cover to cover. Pop out of cover at any time, and there was a pretty good chance you'd die.
More than once, I compared the experience to Metal Gear Solid 3/4. I was crawling prone through bushes, and coming out behind people to knife them, or arm the MCOM.
I absolutely don't want to restart the COD/BF flamewar from earlier, but I think it is fair to say that COD fans will be able to find a mode that suits them, with the faster pace they are used to. Team (infantry) Deathmatch should play the same as it does in a COD game, if that mode ends up being in BF3 (without killstreaks, I assume). For the rest of us, Conquest and Rush are nothing like COD.
