Although Windows 10 Mobile has yet to arrive on a majority of eligible handsets, Microsoft has set an EOL date that will see support for the mobile OS end in 2018



From Neowin:

Although Windows 10 Mobile has been available for Windows Insiders for quite some time, the official release can currently only be found on the Lumia 950 / 950 XL, and has yet to make its way to older Lumia handsets. Despite this, it looks like Microsoft has set an end-of-life (EOL) date for Windows 10 Mobile that will see updates for the mobile OS end in January of 2018.

WinBeta first picked up the news a few hours ago, but since then, Microsoft has changed the EOL date from January 2019 to January 2018, as detailed in the screenshot below, it's not clear why the date has changed a full year overnight.
