I can only talk from the PS3 user perspective, but I feel that the PS3 version was rushed to be out on time. I would have much preferred to wait another few months for a finished article rather than what we got. Its like we are in the beta phase just now beta testing rather than playing the final product.
For me its not anything to do with more realistic shooters or such like coming out. I just wanted a solid, fun to play online experience and to be blunt Crysis 2 simply has not delivered - on any front. I dont see any amount of patching changing this either. It is very clear the route that the devs want to take with this game with the modes/the general gameplay/weapon feel etc and it is just very very disappointing. So far my flop of the year award goes to Crysis 2, BOO!
Ppl keep going on about the ps3 version as if it's infinitely inferior when in reality it's not, with aspects of it superior to 360 version, and only the slight res reduction being the major difference. Apart from that they basically as buggy and messy as each other, and the 360 has an issue with a glitch that adds graininess to whole screen too.
They probably could have optimised ps3 engine bit more, but it's not a case of us just waiting , but their publishers pushing them to release it cause of keeping shareholders happy, avoiding clashes with other big titles and simply not wanting to pay wages for another fee months to fix it further .

This gives insight into ps3 /360 differences and if I look at lens of truth too
