I think it wont be long untill they announce a PS3 demo. They have pulled through on the community demand so far. I wouldnt doubt them.
Yeah but you never know what they might do..
Im with you though, hopefully they will release a MP demo for PS3, because PS3 probably has a bigger base of gamers. Im not saying that the PC is less important because I have a PC aswell and that is where the most crysis fans will be, but if a demo was released on all platforms, it would surely attracted more people to the game..
Anyway, heres hoping for them to release the PS3 demo
