These seem to be the actual promotional images provided through Google. The extra bezel on the XL (black) seems pretty awkward. I may have to spring for the smaller variant, assuming it has an OLED screen.
In the lead up to the October 4 announcement, it seems someone at Canadian operator Bell has pulled the trigger a little early on Google Pixel promotional materials. First spotted by Steve Hemmerstoffer, the carrier seems to have mistakenly put a Pixel render and promotional blurb up on its Galaxy Note 7 business order page. �Bell's not revealing too much, but that Pixel name seems all but confirmed at this point.
