Seeing as XB180 failed at being backwards compatible (yeah, I'll b**** about that whenever and wherever because, hey, why not?), I won't be ditching my 360 either. But none of those titles you mentioned are in my radar. Again, just like they did with the 360, M$ is launching their new toy without a killer exclusive app that gives you a compelling reason to get it the moment it's launched. In the meantime it'll run games that you'll be able to play on your 360. The only remaining exclusive thing they got going for them is Halo and the next game won't be out 'til at least next year.
