I was wondering if an IPIX style -- grab'em by the throat -- tripod head mounting thingy was being considered? Those lenses seem to remain really popular and useful especially as compact cameras commonly exceed 10/12 megapixels and the prospect for a 20 megapixel compact gets stronger every day.

Anything like that in the works?

You could just about use half an NN3 and put a throat grabber on the tilt axis and get a flexible and useful head.
