About the Terpstra keyboard

Hello
I think some people from the list are very interested about this generalized keyboard
that was mentioned a while ago.
I personally can't stand it anymore not being able to play other tunings besides what my piano offers , and I cannot find
any other serious solutions.
I could have bought the Starrlabs microzone but I don't know exactly what will the new keyboard offer , and
how will be different from the microzone.

I know that some people here are involved in this project , so please , can we have some information , news , updates on the
progress of the keyboard making?

I am sorry if I am asking too much , but this is torturing me.
Thanks for your time
