I think the whole LSA thing is a dead end and in retrospect Cessna wishes they never went there. If the FAA get rid of the 3rd class medical then the market for LSA's will instantly disappear.
I agree, the current limited market for LSA aircraft in the US is largely people who can't get a Class 3 medical.
When you can otherwise build or buy an RV for half the price, fly as fast as anything going, climb faster, do aerobatics, fly VFR or IFR, travel thousands of miles all over the country, maintain it yourself and not be constrained to the airframe manufacturer for parts, it hugely limits factory built LSA marketability. The LSA Cub replicas seem to have some traction because they don't have that competition, the rest have no strong business case except the medical issue.
I'm not an RV owner but that seems to me to be the situation.
