I reckon its gonna be around the 2 - 2.5GB mark. Bioshock = 1.8GB Stranglehold = 2GB COD4 = 1.4GB Hellgate: London = 1.5GB GRAW 2 SP = 1.8GB World in Conflict = 1.2GB MoH Airborne = 1.3GB Then theres these less than a GB TimeShift UT3 ET: QW Painkiller: Overdose F.E.A.R. Perseus Mandate Crysis MP Beta rev3 is 1.4GB and is a pretty descent sized map and the SP "contact" level looks about 1.5 - 2x the size but will have DX10 features and the sandbox so im sticken with 2 - 2.5GB in total. Hopefully for quota reasons its smaller than we think. It really depends on the compression type they use also I guess LETS MAKE A COMP FOR THIS TO WIN A $10,000 PC courtesy of "Tell him he's dreaming Corp."
