Earlier this month, a Windows 10 review that was not expected by 2020 was a bit strange. At that time, Microsoft firmly stated that this was due to features that "require longer runtime" without specifying what those features are.
The well-connected Mary Jo Foley tells another story: Exiting is actually a consequence of moving portions of Windows development into the Azure group.

This means, however, that Azure has to catch up and obviously it has shaken a little schedule. The Windows Update April 10, 2019 is almost here, built on the internal communication of December 2018. Usually, this work will be stabilized and baked in a June 2019 release, codenamed Vanadium, which is used as a basis for Xbox, Windows, and Windows Server development in the second half of the year. But this year, the release of June 2019 is overtaken. We will still receive a feature update in October 2019, but this will also be based on the December 2018 issue. The Windows main platform will not see an internal version (codenamed Vibranium) until December 2019.

From then on, things have to go back in the right direction, codenamed manganese in June 2020
