Windows Phone 8 is set to get the Blue update along with the PC version of Windows Blue. But this update to Windows Phone 8 is likely to be delayed until 2014 according to sources.

As previously reported by The Inquisitr, Windows 8 Blue will include performance improvements, a smaller kernel, longer battery life, a better search charm, better screen-size scaling, and improved windowing (with no explanation as to what that may entail). These Windows Blue rumors have triggered a fire sale, with Windows 8 discounts running as high as $100 off or 40 percent off.

Microsoft officials are not commenting on anything having to do with Windows Blue for either PC, tablets, or Windows Phone 8. While it is unconfirmed, some speculate that Blue could also be the update in which Microsoft unifies the API for both Windows Phone 8 and Windows 8.

Ubergizmo reports that a delay should be expected for the Windows Phone 8 Blue update:

“Major smartphone operating system updates seem to be released on a yearly cycle, but it looks like as far as Windows Phone is concerned, its major update for this year could possibly be delayed until 2014. This is according to Mary Jo Foley of the Twit.tv Microsoft Show where it was suggested that the Windows Phone Blue update could be delayed until next year.”

ZDNet reports on what we do know about the Windows Phone 8 Blue plans:

“Windows Blue is believed to be the first of a number of annual operating system updates to Windows 8. There also is a Windows Phone Blue in the works that is expected to have the same core code as Windows Blue. (But, just like the Windows Phone 8 operating system, which was version 8.0, the Windows Phone Blue core build number will likely be something different from Windows 6.3.) Microsoft recently posted job openings for new Windows and Windows Phone team members to work on the Blue release, but have since removed those posts.”
