Here is the image itself.
I don't think it's the Nexus 8. I think it's a rendered display (the
entire front, I'm saying, has been replaced with a rendered image) on top of some tablet that very well might be the Nexus 7 - holding mine at that angle, it looks really similar.
There is no camera visible. I am pretty sure we'd see one.
I'd love a minimal-bezel N8 like this. I hope I'm wrong. But I really, really doubt that the new Nexus 8 was inadvertently leaked on one of android.com's main tabs. I think it was just altered to make the display more readable.
