Re: Kinect 2.0 not requiered...
That being said, the fact of the matter is that Microsoft poured a lot of cash into R&D for Kinect 2. And it costs a lot to make each unit. When you make that kind of expenditure, you don't suddenly throw up your hands and say, "Eh, that was a fun way to spend millions of dollars, now we'll make it optional and toss away any hope of recouping our investment."
Pissing away the millions that Microsoft spent developing the Kinect 2.0 is a hell of a lot better than ending up with the Dreamcast 2.0.
