Title kind of misleading. Of course MS has to change the code base from the 360 to the X1. Architecturally they are very different including the whole 3 prong Hyper V OS.
Also I remember another interview by Crytek stating that when they wanted to move to a different direction with Kinect, MS gave them the OK. It was not MS decision but instead Crytek. Either way, I would guess this is the problem with any launch game. Hardware finished close to launch, software still being tweaked and driver changes pretty much every day.
