The details on this video are scarce but what we can tell you is this is evidently an early release of the Windows Phone 7.8 upgrade for the Nokia Lumia 900.

The video is all of 0:37 seconds, meaning an extensive tour of all the new features is out the door. In fact, there’s not too much one can glean from this outside of the fact that 7.8 looks fast and smooth on the 900. We do see a new Xbox icon and the tile resizing, but nothing else is revealed.

The good news is we probably only have another 60 days or so before we actually have this on our devices.
