it would be between crisis core and god of war... kingdom hearts im psyched for the most but im guess it will be coming early 2009 but if it in 2008 thats my top choice.. between god of war and crisis core i think im going to lean more towards god of war.. ya i have a picture of cloud right now.. in fact my name is cloudXx-CLOUD-xX

Ya, alot of people will lean over to GoW, but I believe that FFVII CC will sell out alot more.
