I hope it's as good as the hype.
I would hate to have jets on some tiny head to head death match size map. I still play BF2 but I've been using AIX 2.0 mod. The mapos are just big enough for jets. If the maps are ArmA 2 size, I see computer upgrades in your futures. We will wait and see. Anyone pre-order yet?
