There has been a lot of speculation online recently about the next major Windows Phone update. Microsoft is reportedly going to show it off at its January 21st event where the spotlight will mainly be on the consumer version of Windows 10. Some reports suggested that Microsoft is not going to release the previously planned Windows Phone 8.1 Update 2 and instead it will bump up devices straight to Windows 10 for smartphones and tablets. However a Bluetooth SIG listing contradicts that possibility.

Just last month Microsoft started rolling out the Lumia Denim update. Windows Phone 8.1 Update 2 was supposed to follow soon after but so far the company hasn’t detained any release roadmap for this update.

Given the fact that Microsoft hasn’t really talked about this update much it is easy to understand while people might come to believe that the company is planning a jump to Windows 10 for smartphones and tablets powered by its operating system.

Windows Phone 8.1 Update 2 is expected to feature support for Snapdragon 805 processors and 2K displays, apart from user interface and performance tweaks. Bluetooth HD support was expected as well which would have made the devices compatible with Bluetooth enabled keyboards.

A certification for Microsoft’s new Bluetooth stack for Windows Phone 8.1 Update 2 was spotted on Bluetooth SIG last month but it later disappeared. This further fueled speculation that Windows 10 will be favored over this update. Now though Bluetooth SIG’s listing is back online again, perhaps to put these rumors to rest, but it can’t really be said for sure.
