Bungie's involvement is the only reason Halo was worth playing at all, and Microsoft interfered with that from the start, so I can't think of anything ood coming out of Microsoft milking an already tired franchise.
What is so hard to understand for so many people? Making more Halo related games when they have been selling best than almost anything else? It's like you want me to believe you would stop selling me a fresher POS even if I would be paying you for it each time you would give me one. And lets not be too funny... Halo is one of the currently greatest franchises. Like it or not.
