Did Microsoft accidently leak the Xbox One’s release date?

Microsoft may have inadvertently leaked the release date for the Xbox One. Originally spotted by OXM, the official Xbox site posted a splash image of Call of Duty: Ghosts for Xbox One along with the November 5, 2013 date.

Now we've known for a while that Ghosts would be released on November 5, but it was thought that would be the current-gen release; however, with the page in question is clearly branded with Xbox One with very little Xbox 360 details.

It's worth noting that the page has since been updated to include both the Xbox One and Xbox 360 versions of the game. This time, the Xbox 360 version is available for pre-order and has the November 5th date above it. The Xbox One version merely says "coming soon!"

So is this a case of mixed messaging or did Microsoft accidently leak the Xbox One's release date? Below are the before and after images of the Xbox site in question.
