Resistance 2, Motorstorm 2 and Siren all say "WTF about me?" They were all unveiled in 2008, and released in 2008.
Also, the recent GoW trailer was gameplay, not CGI.
Now, I wouldn't be at all surprised if GoWIII did come out in 2010, but still, your reasoning is faulty.
Also, I started to reply to everything else you said, but then changed my mind. What's the point? If you're honestly putting DLC, an expansion pack, and a 2008 game against the 6+ awesome PS3 2009 exclusives, and then claiming that the 360 has more good 2009 exclusives ... words just sort of fail me.
