Who said it would only be for the PC?
I don't see why we couldn't atleast drive around some humvees, and maybe hang glider across the buildings if we wanted to. I think that would be pretty sick. Tanks and stuff would be hard to do though without a really large map, and the consoles don't have enough RAM to support large maps. Heck, the map Mesa takes up 1100MB of Ram, and the Windows OS takes another 1000MB, which totals around 2GB of RAM. The consoles only have 512MB for the entire system, which is why large maps are impossible to do.[/quote]
The fact that it wouldn't work on the console is WHY I say it would only be for the PC. Extra man-hours and money into something that would estrange more people than it would convince. The console crowd would certainly be pissed if PC got extra features at initial release, and for good reason. Spending more money to make less is usually not considered smart business. During the E3 interviews, Crytek strongly hinted at DLC for C2, so maybe PC will get exclusive map packs.
And to answer the humvee question: Do you really want to drive a hummer half a block? There won't be room for vehicles to work on small maps. Why ruin the gameplay to force a useless mechanic?
