Earlier today Xbox community manager Raj Patel confirmed that a teaser posted for what looked like an upcoming reveal from Xbox was not official. Patel originally posted the image on Twitter without description, which Neogaf users deciphered as "Presented by Xbox, 10am PDT, 1pm EST, May 4th 2015."
Patel explained that he posted the image to "see what others think of it, not as an endorsement or tease" and apologised for any confusion generated. The image itself looks like a red pause sign, although it could also stand for the Roman numeral for the number two.
Earlier this week Microsoft did make several announcements on Windows 10 and its integration with Xbox One. For a full list of what was shown at the briefing, check out our roundup below.
