The new information is likely to cause a bit of a stir but is to be expected. Here is what you need to know:
- New Insider builds (presumably the RS1 Redstone release branch) will go to the Lumia 550, Lumia950 and Lumia 950 XL first and "expand from there as we release Windows 10 to other devices."
- Windows 10 Mobile general updates for Windows Phone 8.1 hardware is still planned for "early this year" but there are no dates to share just yet
Expanding upon the general Windows 10 Mobile update, Gabriel Aul said the following:
Regarding OneCore (Microsoft's term for a shared OS base), the company is prioritizing certain devices first, but moving all along the same path:
Unfortunately, those still waiting for the Windows 10 Mobile official update are in limbo. It is coming, perhaps even later in February, but it sounds like there is still some testing and finalizing that is occurring. Considering the original plan was to have the update out by the end of 2015 and Microsoft is indeed pushing the update back further and further.
The upcoming Redstone (RS1) release for mobile and those update plans make more sense. Going forward, Microsoft is likely to focus on just its core Lumias released in late 2015 for future OS versions. Doing OS updates and testing on the dozen Lumia models out there is time-consuming and resource intensive.
Still, it's not all doom and gloom as Insiders of all devices will eventually get RS1 as well, just not as quickly.
