"Thirdly all this sounds suspiciously like a "nano" version of a fresnel lens with a very very large number of microscopic ridges. However the mechanism for delaying/bending light may be different. On a Fresnel lens you compromise sharpness."

It does sound very similar, doesn't it. Perhaps sharpness wouldn't be effected given they are working at the "nano" level. Be interesting to see where it heads in the years (decades?) to come.
