During tonight's Halo 5: Guardians launch festivities, Xbox boss Phil Spencer just announced that the Xbox One will receive its Windows 10-based update on November 12th. That's the one that will put a new UI on the console, as well as give everyone the ability to play certain Xbox 360 games. Some Xbox One owners in the preview program has been beta testing the new OS for a few months, and the experience has occasionally been a bit rough. Hopefully all that testing means the bugs are appropriately squished once this software rolls out wide in a couple of weeks. You can see the announcement in the video embedded after the break, or jump to the live broadcast as the Microsoft folks count down to midnight.
