Retailer Zavvi appears to be the first to have gone live with Xbox One pre-orders.
It is currently asking for £399.99 for the new machine. It is also asking £49.99 a piece for a number of games – FIFA 14, NBA Live 14, Madden NFL 25, UFC 14 and Call of Duty: Ghosts.
It should be noted that Forza 5 was tonight confirmed as a launch title for the machine. EA has said the same of Battlefield 4.
Zavvi is currently also charging £399.99 for PS4 pre-orders.
UPDATE: GAME is also taking pre-orders, although it has not confirmed a price. Instead it is accepting deposits for £20.
“Gamers all around the country have been eagerly waiting to find out what Microsoft will be bringing to the table – today we have our answer: not only is the Xbox One a really powerful piece of gaming hardware, it promises the next level in home entertainment," Game Retail's category director Charlotte Knight stated.
"The UK gaming community is obviously excited by the prospect of this next generation console and we can’t wait to see it in action at E3 next month!
“It is worth reminding everyone who’s interested in the Xbox One that many console launches have seen demand significantly outstrip supply, so we would urge anyone wishing to get their hands on a Xbox One from launch to place a deposit with our store teams or online as soon as possible.”
