OnePlus OxygenOS images make rounds

Today we had some leaked images of a OnePlus phone that tends to look like a shot of OxygenOS.
Leaksfly, a twitter handle has leaked images of two different OS running on the OnePlus One.

The first image could be that of the upcoming OxygenOS, where we can see the Oxygen weather app. The image doesn't look very authentic and could be fake. The other makes no sense as it shows the OnePlus One running Windows Phone OS, but it rather looks like a Windows 8 launcher app. Everything was in Chinese on the screen.

OnePlus has already announced the date of release of its OxygenOS which is the 27th of this month. We may get some more images as the dates get closer. What you guys think of these leaked images?
