Microsoft had been expected to have nice and shiny new dual-screen Surface Neo devices in the shops by Christmas.

But Chief Product Officer Panos Panay told his staff that Microsoft wouldn't be delivering its own Surface Neo dual-screen 10X devices this calendar year.

In addition, Microsoft also won't be enabling third-party dual-screen Windows devices to ship with 10X in calendar 2020r.

Vole wants to get Windows 10X on single-screen devices first and it might even be planning to delay its Android-based Surface Duo to some time beyond this holiday season.

In late February 2020, Microsoft officials warned that the COVID-19 coronavirus was affecting the company's China-based supply chain.

For those who came in late, Windows 10X is a variant of Windows 10. It was formerly known by the Windows Lite/Santorini codenames.

Microsoft officials have said publicly that Windows 10X is for dual-screen devices only, but privately, Microsoft has been working on making Windows 10X work on single screen/clamshell devices.
