In what could be an accidental slip up by Microsoft general manager, Brian Hall, he said that the new Xbox will be shipping with Windows 8.
This is the full quote (as transcribed by WeGotLife):
“We’ve had Hotmail and operated Hotmail for about 16 years, we obviously have Exchange, and Outlook, that people use at work. We just decided it was time to do something new and bring the best from each of those and put them together and release it right in time for the new wave of products that we could have coming out with Windows 8, with the new version of Office with the new Windows phone and the new Xbox.”
The quote can be heard in the video below from the 1 minute 17 seconds mark.
