Digital Foundry's analysis is up:http://www.eurogamer.net/articles/digitalfoundry-crysis2-face-off
After all the bullshit I read on the net about the PS3 version I'm surprised that they are pretty much identical. Frame-rate is all over the place though, average frame-rate is definitely higher on 360 but on the more intense scenes it drops all the way down to 16fps...
3D looks better on the PS3 thanks to HDMI 1.4, it's still that fake 3D though where they create different layers for the HUD, view weapon and background and introduce pixel separation to give the illusion of depth, it's not stereoscopic. I don't have a 3D tv so that irrelevant to me anyway.
The campaign looks interesting so I might pick this up after a price drop or wait untill I buy a new PC.
They're showing off the engine at the expanse of the frame-rate to the point where it significantly impacts the gameplay. He even says that you should use stealth in some sections because triggering a fire fight makes the game almost unplayable, that's ridiculous.
