When talking about some Pro2, if it would just hypotheticaly come one day.. There won´t be any backers in the beginning and maybe also no need of preorders. If they will sometime make another device, then it will be definitely only when the first one succeeded. And therefore they should have some money from the company profit. What I mean, they should prepare the second device quietly and then introduce it just before the final products are leading to the factory line. When you try to date it on nowadays PRO1 and what we know about the production status: If I were them, I would show the new device (just imagine it is this year) on IFA Berlin 2019. That means some two/three months before you can fully purchase (well at least what FxTec says for Pro1). And after the IFA show, there MAY be preorder availible. Just for two months.. I am pretty sure that the plan was like this - preorders much closer to the production date, but it was for the first time and many many things happened. So lets see if some successor will come and whether the circumstances will change 🙂 I hope the answer will be positive. Lets see after few years.
