Windows 10 for desktops and mobile devices is just around the corner.
That would be July 29th if you’ve been on vacation! –>
And … the next version of Windows Server will be Windows Server 2016.
The current version is Windows Server 2012, which includes a specific (post-SBS) version called Windows Server 2012 R2 Essentials.
So, it is only fair to have people ask: “Will there be also be a Windows Server 2016 Essentials (W2016E for short) released?”
The following public Technet article mentions W2016E by name. So it would be a reasonable conclusion to think that they are planning on a W2016E version.
But — given that Server 2016 will not be rolled out until next year, things can always change.
