In conjunction to the Windows 10 reveal event held in January, Microsoft also plans on showcasing changes to the Xbox One dashboard that are more in-line with Windows 10.

According to Microsoft Product Reviews, the rumored dashboard update would feature the ability to run Universal apps on the console. Even thought its just a rumor at this point, Microsoft is expected to release a statement regarding this event sometime in December.

Major Nelson said recently that Microsoft would be ramping down the severity of November and Decembers updates for the Holidays. So, it could be more that possible that Microsoft would indeed be working on something else under the hood.
