If I want KINECT, what do I need to buy? an XBOX 360 and what else, please help?

Okay, so I believe the new KINECT system is a completeley different machine the only reason it's still called the 360 is because it looks roughly the same (a few adjustments) and it is still the same system. But I don't think you buy an X-box and a different product. This probably won't git off too well for Microsoft, even though they had the technology to make it a seperate product worth about 40-50 quid they are too greedy. I believe it will probably be around �250 up to �300 at the most.
