Upcoming exclusives for Xbox 360?

I feel that I don't really use my Xbox 360 anymore ever since I got a PS3. Are there any good exclusives coming out any time soon?

There's also a new GTA IV episode arriving at the end of the month.

Splinter Cell Conviction will be awesome.

Why do you need exclusives to play the 360? Multiplats are notoriously better for the 360. I mean, right now I am all PS3, but I am getting Borderlands for my 360. Personally, I would rather not play it then play it on the PS3... that controller is terrible for FPS.
