I wouldn't hold my breath. I'd like to see the patch, but I don't think it will be coming out at all. And no, it would NOT make it look much better, because all the in-game assets are already in place. Adding one or two shader effects wouldn't change anything. Crytek would have to remake the game if they wanted it to look better on PCs, but of course they're not gonna do that.
They sold out, in my opinion. Not surprising, but still disappointing. And I gotta say the graphics don't bother me- the game still looks good. What bothers me is the gameplay, small levels and the nanosuit for idiots. If you got the hang of using the nanosuit in Crysis 1, you could sprint into a group of Koreans and knock one of them over, switch into strength and grab another one, throw him into the third one, and bitch-slap the last one. Nothing like that is possible in C2. Having to hold down the melee key for a power strike!? WTF!? It makes no sense! When your enemy is ten inches away from you, the last thing you wanna do is to hold down a key and wait for the melee attack to charge up, even if it only takes a second.
Baah, enough ranting.
