Killzone 2 or Halo Wars: Which will sell more and by how much?

[Impulsivity]

I would bet on Killzone Worldwide especially because I'm sure the reviews will be better.

Has anyone played a good console RTS ever? Even the ports of otherwise good PC games like Command and Conquer just play like crap on consoles, ESPECIALLY the Xbox which never has gotten it together for mouse/keyboard support.

In theory the PS3 can be decent for RTS games if they include support for mouse+keyboard (will be interesting to see if C&C3:RE includes it with the expanded PS3 version). Playing with a controller is just slow and awful.

Also why would anyone who loves sci fi RTS games be jonesing for Halo anyway? Dawn of War 2 is coming out followed by Starcraft 2! If there was ever a time to release Halo Wars it was last year before those two juggernauts hit the scene.
