I do think 360 will win 2012, why you may ask? Well first I think an early $50 price cut on Kinect will happen around Feb.-March to give the 360 a short boost. Next, Star Wars Kinect release along with the Bundle will give it a slight boost. Then at E3 MS will drop the console price by $100. Halo 4 bundle and next COD bundle will give a huge boost. Along with exclusive list consisting of Halo 4, Fable Journey, Ryse, Witcher 2, will push it over the Ps3 and Wii.
Now I could be wrong because after all this is a prediction, but I'm sure atleast two of these things will happen.
