Halo: Chronicles VS Killzone 2 = Xbox360 win

 Interesting way to look at it.

There is also too human, which apparantly is being released 1 week after GTA- so thats possibly dead (sales wise).  And Ninja Gaiden, possibly fable 2.

For PS3 there is also Resistance 2, as stated.

So..

Gears of War 2 vs Resistance 2 ,     very close- but sales will edge in favor of Gears I think. (360win)

Dead or Alive 5 vs Tekken 6 (PS3 win)

Forza vs GT (PS3 win in a big way)

then there is Haze, Killzone  vs. Ninja Gaiden 2, Fable 2 ..  but who knows when they will actually be released.

purely comparing those last 4 games, I would say PS3 win, but I could definately be wrong.  There are alot of variables there.
