I really wanted this, but after the second demo it seems way too hectic for me. OFP works because you can walk for a mile without seeing a soul, then get hammered. Or you can spot a scout at 500m away and take a potshot at him, or slip silently, (like deathly silent), through a jungle and shoot at shadows.
This game has walls and keeps you far too tight. Guess they do this so you don't get bored, but result is you don't even get a second to take a breather. It's like an MTV commercial to some degree, definately for the kiddies.
Myself, I need a little silence in a game, to contrast the fighting and up the anxiety. This seems just go go go like an fps DM map.
