A user has apparently got his hands on an Xbox One and is tweeting information about the console which is actually due for release on November 22nd. Microsoft have since banned his console meaning he won't be able to access several online features, something that the Xbox One is touting for sometime now.
However a Xbox Dev believes that the ban is necessary as it may lead to misinformation and PR disasters. He also stated that the Microsoft reserves the right to ban any Unreleased/Beta Consoles under their terms of service.
"He did buy a product, a product not released until the 22nd. The product was delivered in error, but that doesn't change the fact it's an unreleased product and most likely classified as a beta product. Microsoft reserves the right to suspend/ban that console under the TOS.
That being said, I was ambivalent about the leaks we saw today. Leaks are seldom good for the development team, even if they are positive. It represents thousands of hours of work that may or may not be in an unfinished state. All it takes is one instance of something that was mis-communicated or misconstrued, throw that through the internet media machine and you've got a disaster.
On the flip side, it was quite refreshing and encouraging to see everything we've done received so well. It was a little emotional for me when I saw numerous approving responses to Marc and Yusif's demo yesterday morning. I think many of us on the team sometimes forget to take a step back and see the product work as a whole because when you work on the console, all you see are the features that still need work and the bugs that need fixing. At least this was the case for the past 6 months or so."
Personally, I hope it's only a temporary suspension until launch day.
