Generally, if a Kickstarter reaches mass market, and to clarify, this bell's $200+K is not mass market, the price could come down. I have seen Kickstarter items lower their price after they have moved successfully to the mass market. The current $35 "price" covers development costs in addition to production costs. Development costs can be significant, and any smart person on Kickstarter would want to cover those knowing after the Kickstarter experience, their product could die.
That said, price is determined by what the market will bear. If they go mass-market and people are willing to pay $35, they would be fools to lower their price. It is not like they could raise their price to $40 without backlash.
