Bill, $$700 uberlight tech bindings have been selling very well amongst the rando race crowd for over a decade. They've been bleeding over into fast ski mountaineering as well, for the well healed.
However, I think a binding with the features and weight of the Speed or Vertical lines would sell the most, especially if someone managed to undercut Dynafits pricing. I'd be in line, as I'm still skiing 3 pins mainly because they're 50 bucks a set, rather than 300.
