Xbox One, the upcoming next generation console from Microsoft is rumoured to be costing £399 and will ship on November 30 in the U.K. after a leak from online retailer Zavvi.

Xbox One, which was announced yesterday at Microsoft’s conference, has seen its first major slip up from distributors in the form of a U.K. based online retailer, Zavvi.

The leak was noticed earlier today, and is still live on their current website. We expect the conversion of £399 to $399, to be around the same figure, competing with the Sony Playstation 4, and will possibly make the Xbox One cheaper.

The page also suggests that Xbox One’s release date will be November 30, which is relatively realistic due to the console being released in the fourth quarter of this year, providing everything heads smoothly.

However, these price details have not been confirmed by Microsoft but we do expect the announcement to be made at E3 2013 starting on June 11.

To recap on the news of the Xbox One, this will be Microsoft’s newest console in 8 years, after the birth of the Xbox 360 in 2005. The 360 console has been through several generations and has evolved as audience preferences change, from it being launched as a games console, to now becoming a leading home multi-media entertainment device.

This was the message that Microsoft clearly pushed at yesterday’s conference, with the idea of the Xbox One being more “TV” than gaming, but to be a leading all rounder within the home.

We’ve kindly provided a report on all you need to know about about the new Xbox One, with all the hardware, games and user interface changes that were announced yesterday.

Would you pay £399/$399 for the Xbox One? What are you most excited about regarding Microsoft’s latest venture? Or, is this something you couldn’t imagine owning?

Xbox One will be released on November 30 with a price of £399/$399 which we hope will be confirmed at E3 in the next coming weeks.
