Nah, I don't think these images of the new maps are genuine! First off the community map design competition doesn't close until March 30th, and why would community and IW devs waste all that time blabbering about new maps when they are simply copy and pasted from the campaign?
Maps 2 & 3 were pulled straight from the campaign, and Infinity Ward said only a fraction of maps will be from story mode, the rest completely brand new. Map 2 looks a lot like a modern take on Toujane from Call Of Duty 2! I'll be annoyed if those are the genuine maps, they're a bit drab and uninspired and not worth the wait, I played through most of them already in campaign mode!
