Microsoft launched the new console in the UK on 16 July, but within a day the device had sold out in many retailers across the country.
According to the report, Electronic Theatre contacted a number of stockists across the UK, finding that the Xbox 360 S had sold out. One retailer told them that it had "greatly underestimated the demand for the new unit."
Microsoft has announced that it will no longer be taking advance booking orders for the console after the first stock has sold out within two days, and that the Xbox 360 S will now be sold on a first come, first served basis.
Retailers including Tesco Direct, Sainsbury’s and GAME have hinted that they expect the next shipment to arrive early next week.
