Price is one of the main reasons why many woodworkers today do not own a SawStop saw (despite it being the #1 selling cabinet saw these days in N.A.; by 2014, 50,000 SS were sold). We cannot discuss safety in isolation. It is not about racing to the bottom, but about SawStop or Reaxx (in due course) competing against a new, perhaps more powerful competitor.
I am not talking about competition between Felder (sliding saw manufacturer) and SawStop (cabinet and smaller saw manufacturer). Having learned their costly lesson, other table saw makers (presumably wiser now) would be more than willing to adopt Felder's innovation if it is technically feasible, and if Felder licenses the technology to them. The competition will be between SawStop and other table saw makers who are licensed to use the Felder's innovation.
Between replacing a cartridge/damaged blade (SawStop method), and a 15-second reset (Felder's, details unknown yet, presumably at no extra cost to the user per activation), a future cabinet saw buyer would prefer the latter, every other consideration being the same. This would be why SawStop will have to reduce its prices (profit margins accordingly) to compete. We are not talking about SawStop compromising its safety feature or sawing quality given a reduction in price.
Of course, if other table saw makers incorporated the Felder's technology in a poorly built saw, SawStop would have much less to worry about. But I don't anticipate that to be the case. I spent a lot on my SawStop not solely for its safety feature, but more for its sawing quality and repeatability.
