Xbox 720?

IGN sources have stated that the manufacture of the next Xbox is estimated to begin in late 2012, with a launch date set for late October/November 2013.

So, how will the next generation of Xbox differ from its predecessor?
Rumour has it that it’ll be six times as powerful, with a Radeon HD 6670 under the bonnet. HD 6670 has outputs for several displays, DirectX 11, 1080p HD out and 3D as well. This also means that this new games console from Microsoft will have 20% better performance than Nintendo’s future “Wii U”.

What the next Xbox will be called, when a launch date will be confirmed and what it’ll cost are all unknowns as yet.
