According to a new job listing from Microsoft, the next release of Windows Phone is targeted for the upcoming holiday season. Microsoft has yet to reveal any details about this 'release' but we do know that Windows Phone Blue is currently being worked on.
"This is a great time to join as we’re completing our current release are getting ready for our next release targeting the holiday of this year and we’re chartered with keeping the momentum for Windows Phone by bringing new killer devices and delightful user experiences. There are enormous growth opportunities in this role and organization," Microsoft mentions in a job listing. No details have been revealed on this particular update but one can assume Microsoft is referring to Windows Blue.
Windows Phone Blue, on the other hand, is expected to tie Microsoft's major platforms such as Windows 8, Windows Phone, and Windows RT, and allow for a new programming interface, kernel updates, and other minor user interface enhancements.
