The source is questionable at best. However if this does prove to be true, I'm fairly sure it will involve Microsoft's new plan of buying exclusivity of games as opposed to developing it themselves. I don't know the cost differentiation between the two avenues but I could see this being a good way to move in. I can't vouch for this particular title being a good pick though. MS should be buying out devs to make titles for IPs that MS owns themselves.
