A newly leaked Nokia marketing video features what appear to be some early Windows Phone 7 prototypes. These bear more resemblance to the first designs than the more recent Sea Ray device which has also been caught on video.
The video appears be an early marketing concept video. A couple of signs point to its age. The version of Bing shown off comes with three buttons whereas the Mango version will feature four. There is also an Ovi-branded tile despite Nokia having announced plans to phase out this brand.
Assuming that the video is legit, it remains to be seen if we are seeing concepts that have now evolved into new devices or if we will see such models in 2012.
