The 1tb Xbox One also comes with a redesigned controller, which appears to basically be the same as the old one but with a universal headset jack in the bottom in addition to the current proprietary one.
Sony may also be working on a 1 TB PS4 as well and they’ll announce it at E3 as well, selling the ITB model for $399 and knocking the price of the standard 500 gb down to $350 to achieve price parity with the current Xbox One. If this 1tb Xbox One does in fact launch for $399.99, that would mean both consoles would be selling for similar amounts across both hard drive sizes. The Xbox One has momentarily gained momentum by selling at $50 less .
