Is price really how folks decide which to buy? Even if a couple hundred dollars separates them, it does not change my choice.
We'll have to wait and see how this translates into sales, but Sony won a lot of points for not caving to publishers on these issues.
I suspect a lot of gamers also aren't keen on the Kinect, so the extra $100 for it is another downside.
Unless they make a very overt overture towards the end of the life of that console ... In 15-20 years time, when the servers go down and the lights go out. It will be a useless piece of plastic.
Hell, in 15-20 years time even the non-collectors who hung onto their consoles will be screwed.
Unless the pirates manage to save it from obsolescence.
