Microsoft not fully committed, or, more likely, they need full horsepower for the game.

It's one of the speculations for what finally pushed Bungie over the edge to demanding out from under MS control. The fact that MS appears to have an internal directive that all internal studios must produce a Natal game or include Natal controls in their game.
And I don't think Bungie wanted to compromise anything in Reach with regards to the core userbase. So easy way out for them was to either have much of the company leave en masse, or for MS to release control.
Again, not the only reason they wanted more freedom. But speculation that it was the straw that broke the donkey's back.
