Not sure what is wrong with the price guys? I'd see it sell for £400 really, the rrp is £429. Even so, the 360 was just less than £300 and that was 8 years ago, price up your inevitable car comparisons (intentionally silly statement) or more relative, how you pack of space raiders was 10p and is now at least 20p, be thankful the one isn't £600 by that logic.
Admittedly I wont be paying more than £380 though by the sounds of it, I get 10% off to sweeten the deal. Not sure if I can be arsed buying though, I barely 360 atm, what does the new 360 look like? Might get one of them to console
