Edit: Yeah, Yeah, Activision, i've spent so much time on MW & BF, i know the difference, but believe me, when i saw these screenshots, i thought about EA Command & Conquer Generals 2, with the drones (similar to USA faction drones on Generals 1, it really looks like a US soldier supported by vehicles battle drones), the setting (near future with advanced weapons but not too futuristic), etc :/
