sony won't dominate-not in the usa
Microsoft invested 500 mio in kinect advertising,and though kinect doesn't work half as good as promised and has no system seller ,nothing interessting or innovative to offer and is pretty meh after 2 hours of gaming(like all casual stuff) the system is selling well-just because of massive marketing.
the xbox 3 will be much closer to peoples expectation than crappy kinect(as long as kinect 2 is not integrated-than the hardware will be pretty weak to compensate kinect 2 cost),combined with a 1 billion dollar marketing campaign the xbox should become the best seller (in the usa).
