Huh? There was no Kickstarter, just pre-orders. And when they announced the Round they said that anyone who preordered a PT2 can flip their pre-order and keep their place in line.

My guess is that part of the reason they decided to make the round is that they got so much interest in Pebbles in general, and so many requests for the Round specifically. I don't think they would have wanted to take the risk from the beginning without knowing the demand.
