The first model is going to be expensive because everything is new. Molds, machining, parts, etc. Once a season of production is under their feet, the price is likely to fall a bit, and they may release a heavier/cheaper model with cheaper materials (steel/aluminum instead of carbon/titanium).
Rumor has it the cool new toe piece will also carry over into some of the lower din options, which is really what I want. I don't ever ride with a DIN past 12, and touring I never ride much past 8. A 12 din dynafit feels fine for me 99% of the time, but I would love a better toe piece.
