EDIT: Has no one here bought the game? I just got it today and... HOLY CRAP... the game is freakin awesome! (Especially the multiplayer too!)
I got it. It unlocked for me last night at midnight. Bad timing since I needed to prepare for a meeting the next morning, did manage to squeeze in a few hours of game time.

It's...well, I can run it with lowest on everything with 30-40 fps, a lot of stuff just doesn't work as good as Call of Duty. FOV was bad until I manually adjusted it, sensitivity while aiming down your sight was way too sensitive compared to the sensitivity while just walking, FOV while running is fine though. Then there's the piece-of-shit system that is leaning. Why implement it? I don't need to lean, I've learned to do it manually throughout the years playing Call of Duty. Apparently, it was in Crysis too, didn't really notice it though.
Honestly, the PC is like bad, very bad compared to the PC versions of Crysis and Crysis Warhead. A lot of features which are associated with PC gaming are removed. Hell even Resident Evil 5 had more graphic settings. Autosave or autoload isn't even available. And an option to disable motion blur isn't even there, I've seen several people getting headaches due to that feature.
The graphics are beautiful though, too bad I can't run a 1280x720 res to take advantage of my entire screen.
All in all, Crysis 2 doesn't deserve the hype it got, I can't say I'm enjoying it like other games. Disappointment of the year so far.
