A console only really needs one top flagship FPS. What Microsoft appears to be doing with Gears and Halo is to try to make it two, so they can have two titles so they have a new game coming out every year in the 3D shooter realm (FPS and TPS). With the case of Sony, they really only need one. That can be Resistance or Killzone. Apparently Resistance has been rejected for the flagship name, based on comments here, so maybe Killzone can fit into the mix. Well, Socom used to fit into this also, and was likely Sony's flagship FPS. However, the word now is that Socom was wrecked by Sony, so maybe Killzone can jump in.
Again, I say a console maker needs really only one in each genre, the way Sony has Gran Turismo (for driving games). Apparently Microsoft again in another niche wants to go for to. Project Gotham has been turned into the arcade offering, while Forza appears to be more on the sim side.
Having a flagship title in every genre helps keep the console owner happen, and discourages them from defecting. I would take Microsoft wants Ninja Blade to go after God of War.
