Leak: Windows Phone BLUE Demoed On Nokia Lumia 920; Real Or Fake?

An all new video has been uploaded on YouTube reportedly demonstrating the Windows Phone Blue update on a white Nokia Lumia 920, which is pretty far from a release as of now.

This blurry video shows off a Nokia Lumia 920 but it seems to have folders and a swipe down notification centre it seems.
The video has been uploaded to a new channel called mati leaks which further raises questions about the legitimacy of the leaked video.

Notice that the notification centre pushes the status bar down. Some aspects of this leak were recently revealed in an eBay-purchased Lumia 920 that had an early test build on board. That device was later reclaimed by Microsoft, confirming its authenticity. However, certain aspects of that build, including the notification center, were either removed or later altered, showing that this Microsoft’s plans for the future of Windows Phone 8 are still in motion.

Windows Phone 8.1 aka Windows Phone Blue, is considered to be a milestone update for the OS, but is not due until later in 2013, even possibly into 2014.
