For Photokina: new Nikon 1 18.5mm f/1.8 mirrorless lens

In addition to the D600, for Photokina 2012 Nikon will announce also a new Nikkor 1 18.5mm f/1.8 mirrorless lens (50mm equivalent). The lens will have one aspherical element. I believe the new lens will look like the pictured Nikon 1 concept prime lens that was on display at the PDN show in New York last year.
