That trailer was interesting to say the least. Honestly, the whole Sino-US conflict reminds me too much of Battlefield 2, and the whole "fighting for oil and natural resources" is a bit too cliche. I think that Arma 2, with its setting having many interesting parallels to the Ossetian conflict, is ahead of Operation Flashpoint 2 in terms of the location and conflict. The gameplay depicted in this trailer was alot better than the gameplay shown at E3 though.
