It's possible, but not likely, and if I was in Sony's shoes, I wouldn't want to risk getting swallowed in the Halo hype. Why not wait a week or two, when the hype has died down? That gives them the spotlight. Halo is launched, it sold out, people have played it, they know how it feels and looks. Then ... Killzone 2 is in your face, media is hyping it cause a demo is released.
In my humble opinion, it would be wiser to get your own stage, rather than risk sharing it with another.
