I will make a prediction: either the first batch is enough of a success that more will be made, or so many people will cancel that funds run completely dry and production is halted before the first final final FINAL one is created, and no one gets one, although I'm sure parts will be liquidated off to try and reduce the debt.
So the risk in canceling is not that there won't be a second batch, but in that there won't even be a first.
That's just my prediction though, I see no logical reason for anything but these two outcomes.
