This game looks just fantastic! The multi player looks great, the single player looks amazing, and I can't wait to try that co-op. Really wish I could get something similar to the insane edition for the 360 :(
I was gonna write "I don't share this recurrent concern, except for the wall hack view, the enemy sight (and shooting) indicators and the objective marker", but then I realized I agree with you.
I do like, though, that you are able to observe and mark the enemies before engaging. I just think the wall hack is overpowered. It could be only a hint of his position.
Arma does something interesting: it shows the indication of shooting on the screen, like Far Cry, but if it is outside your field of view, you don't know if it is friendly or not. You have to turn and look.
This really seems to be Xbox 360 footage, doesn't it? It looks mighty mighty fine, awesome draw distance and just great graphics overall. You do clearly see some framedrops and blurring while the character moves and that reminds me of console games, but that's ok. I remember PC footage and that looks quite different.
But if it looks like this on my tv in december on 360...i'm happy as hell.
