I always thought MS had first right of refusal, and Bungie's words in those interviews don't necessarily contradict that.
It could be MS was interested in the game, but not Bungie's demands (dev cut, marketing, budget, etc), while Activision, still reeling from the IW fiasco, was desperate enough to give Bungie whatever they asked for (knowing full well they could drill Bungie in the ass at a later date).
Or it could be that MS thought thought the game was a turd, but Activision didn't.
Or I could be totally wrong about all of it.
We'll probably never know. It'll be interesting to see how it all turns out though.
