Quote by Zeph:
It would be understandable for Crytek to possibly open the way for custom content to make its way to the PS3, but Microsoft has such strict standards concerning content patches on the 360 and XBL for quality control that it'd never see the light of day.
The 360 version of FC2 is no different than all other versions, and the 360 has no problem sharing user created maps.
The only reason I doubt this will ever happen with Crysis 2 is because it was never planned, and Crytek won't bother.
The three systems have way too different specs, and the PC users that will create content for C2 will create stuff that's WAY past both the PS3 and the 360's limits.
