No confirmed release schedule of these updates has been shared but new information certainly points at the estimated time of arrival. A Twitter user named Qxerro has shared tidbits of information about the Windows Phone 8 GDR3, Windows Phone 8.1 Blue and Cortana over the social network.

Certain features will be limited only to the hardware with 1 GB or higher RAM. Windows Phone 8 GDR3 might be packaged as Bittersweet Shimmer on Nokia’s Lumia devices.
Cortana, personal digital assistant for Windows Phone devices, is expected to arrive with the Windows Phone 8.1 Blue update. Windows Phone 8.1 Blue update will initially be released for the US region. In the rest of the world, Windows Phone 8.1 Blue might be released in the latter part 2014. Not only that, Nokia Pro Cam app and Glance screen feature will not even be available to all Windows Phone devices.
