I figure they stopped doing them altogether, cos of the coating flaking off, especially on half jackets, it was covered under warranty, so it cost them too much to replace. There is a customer who comes in my shop all the time and has gone through like 6 pairs of half jackets cos he is crap at changing the lenses, despite my attempts to teach him.
I think they stopped making the other ones too, cos if you got scratched lenses, it was too easy to flake off a bit of paint and get a whole new pair under warranty.
