I think that clearly he is trying to expand the market AWAY from "technical" diving whatever that may consist of and move into a broader segment of scuba divers who may travel and experience a variety of air/water temperatures and needs. To me, 70 degree water temps is cold enough I would consider strongly a drysuit if it were priced competitve to a wetsuit and light and flexible. Once the water temp hits the 80s though I would probably not use one unless there were other factors but then again I might, if it is light and thin and super flexible and form fitting--maybe--oh--and I don't have to lead up.
