Here at Ars, we're old enough to remember when Microsoft first claimed that full support for keyboard/mouse controls on Xbox One was "months away." (That was over 27 months ago, for those still keeping track.)
In any case, Microsoft has announced via a Tuesday blog post that the long-promised mouse and keyboard support will finally be rolling out for Xbox Insider members "in the coming weeks." That could mean the feature is 27 weeks away, we suppose, but Microsoft also promises more information during a November 10 presentation of its Inside Xbox video series, less than seven weeks away.
Microsoft's description of the features bears a striking resemblance to the details shared in a recent developer presentation which leaked back in June. That includes a partnership with Razer to promote the feature and the fact that mouse and keyboard support on Xbox One will remain very much optional for developers.
