I would have to say that the games that I would most be looking forward to at the minute are
Haze
Assassins Creed
However, there is one major problem.
Until Sony improve the wifi card in the PS3 and guarantee a wireless internet connection (unlike the randomness of the current one) I wont be buying a PS3. Why? Well I cannot physically connect a PS3 to the internet without making major modifications to my home's electrical system and I am happy to wait until Sony issue V3 of the machine (as Euro model is effectively V2). Afterall there were several modifications of the original playstation (the 1000, 3000, 5000, 7000 & 9000 series machines) so why not the same with the 3rd generation console?
