Microsoft's Xbox One has begun quietly showing up in stock at retailers, though availability of the strongly-selling console is expected to remain relatively constrained in the run up to the holidays. Stock of the Xbox One is available at Amazon at time of writing, priced at $499.99, following Microsoft's promise to free up more of the consoles made earlier today.
Exactly how long that stock will last is unclear, especially when would-be gamers catch sight of the availability. Amazon sent out an email blast earlier today in advance of sales resuming, suggesting that the store would have more units at some point on Tuesday, though did not specify a time.
Before the new batch of units arrived, new Xbox One consoles were being offered by third-party marketplace sellers for in excess of $1,800. Microsoft launched the console in thirteen countries simultaneously, only to find itself unable to meet demand.
Despite that level of interest, Microsoft won't say exactly how many consoles it has sold in the few weeks it has been on the market. Whereas Sony announced earlier that it had sold 2.1m PlayStation 4 consoles worldwide, Microsoft opted to express sales in less specific gaming achievements, such as zombies killed.
It's possible that the company is simply waiting on official NPD figures before it talks specific sales, and Microsoft did insist that the Xbox One was "record breaking" for the firm.
Other online retailers are still showing the Xbox One out of stock, and it's not known how many more units Amazon has. The retailer's product page is already suggesting that the console is seeing "extremely high demand."
