Microsoft officials supposedly have decided on the final name for Windows Blue. The final decision, one of my sources told me, is that it will be Windows 8.1.
The client version of Blue, codenamed Windows Blue, is a refresh of Windows 8. It is expected to be released to manufacturing around August of this year. As I've blogged a few times, Microsoft is planning to position Blue as part of the Windows 8 wave, not as Windows 9.
"Well, maybe that's not an April Fools' joke," AngelWZR tweeted.
My Blue source said that the top-level branding will be "Windows 8" when Microsoft releases the 8.1 update — similar to the way that Microsoft's Windows Phone officials talked about the "Mango" (Windows Phone 7.5) release as part of the Windows Phone 7 family.
My tipster also says that Microsoft plans to refer to the Blue update for Windows RT as "Windows RT 8.1."
There's no word as to what, if anything, Microsoft plans to charge existing Windows 8 and Windows RT customers for Blue.
If it pans out that Microsoft has, indeed, opted for Blue to be named 8.1 — rather than 8.5 or 8.7 — I wouldn't be suprised to see the expected next couple of annual Windows client refreshes to also have an 8.X name when they roll out over the next few years.
