From 2 separate interviews i read from a couple moths back, it specifically said 'for a period of time' (not sure on the exact wording, but it was along those lines). Basically, timed exclusives. Now, that's not to say that there won't be [i]some[/i] true exclusive content, however, as i mentioned before, don't expect it to be anything you'd really miss being on either of the XBs. I, too, will be on XB. It doesn't bother me at all that the PS platforms are getting some stuff early, or even some stuff specifically just for them. We know what Bungie is capable of, where as a lot of the PS guys may have never really played all through the Halo series. Let them get some stuff just to say 'Welcome to Bungie games.' You'll still get a game worth playing, and so will they.
