They're BA-ACK!

That's right Xbox One fans. News broke today that Xbox One preorders have returned to both the Gamestop and Amazon websites, a good indication that Microsoft is pulling out all the stop for the upcoming Nov. 22 release date to ensure that everyone who wants an Xbox One can get an Xbox One.

Amazon lists the standard Xbox One as available, but the console won't ship until Dec. 31, more than a month after the Xbox One hits shelves on Nov. 22. The Day One edition, which includes a special controller and achievement points, is still sold out. GameSpot, however, now has several Day One bundle packs available and lists a ship date of Nov. 22. Other retailers like Best Buy, Wal-Mart and the Microsoft Store are still sold out.

According to Microsoft corporate vice president Phil Harrison, an Xbox One preorder shortage is all but a certainty for launch sales and possibly even into the holiday 2013 season. He spoke with Eurogamer about the Xbox One preorder launch and the overall availability of the next gen system this year.

"Inevitably, there will be situations where demand outstrips supply. But we work hard to minimize the impact of that," he said. "Pre-orders have been unprecedented. It will mean Xbox One by far and away the largest launch we've ever done on a global basis and on a UK basis. And we work carefully with our retail partners to make sure we have as much capacity and inventory as possible."

In the U.S., though, an Xbox One preorder shortage might not happen at all. At least, that's the hope of Phil Spencer, the head of Microsoft Studios. He told OXM that the company is trying to meet all demand for consoles in the States.

"There might be a line," he said, "but I don't want it to be that if you didn't pre-order in September, you can't get one."

As we approach the Xbox One release date it looks as though fans who were hoping to get a Day One addition might be out of luck. With most of the preoder sites sold out already and the remaining few on the Gamestop site sure to snatched up in the next few weeks it appears that if you're hoping to get an Xbox One Day One edition your options are running out fast.
