"FX" 50mm f1.4 with "speedbooster" (wide angle converter). Would only make sense with an APS-C MILC?? (because the wide angle converter needs space between camera and lens)
Maybe Nikon is realizing that the Nikon 1 series won't cut it in future?

Yep. Google translate is aweful as always, but I think the blog post states that the patented lens would be incompatible with SLRs.

This would be SLR-incompatible. The overall length is >> the focal length so the backfocus must be short.
