Samsung NX 20mm f2 pancake lens killed by PetaPixel (updated)

UPDATE: Petapixel dissects the image that made the internet rounds and points out why it is a fake. Pancake party ruined! Now back to bazooka zooms ;-)

The Rice High blog points to a picture at imageshack.us that shows what looks like a Samsung NX 20mm f2 pancake lens. As usual, please treat this as a rumor, unless or until it is officially announced.
