Lyra...what's with their new line...what new line??

Seems like Lyra cartridges have hit a wall..in the past, and like many other cartridge manufacturer's, we were treated to a new model every couple of years...
Lyra seemingly hasn't revamped their line ( well yes, I know they have recently come out with ultra low output models..ie their Etna SL; but these are still basically the same cartridge with less winding of the coil) in years now! What gives...thoughts??
