Had a Thought About Black Ops

Most of you probably know that the Call of Duty Black Ops is going to be 3D. 3D is the new thing for Sony's PlayStation console, so why is Black Ops 3D for Xbox and PC? Well I have a hunch. Microsoft has a lot of money and invest a lot of money in the Call of Duty franchise, just look at the huge deal they made just so that they could have DLC first. Anyway, I think that Microsoft (owners of both PC and Xbox) paid a large sum of money again so they could keep up with PlayStation. Spending money to keep up when they can't get new ideas for business. What do you all think? Tell me in the comments.
