SC2 price increase?

I have been receiving email from Derek Spears Design that this batch order is the last before Granite Devices raises prices after Jan 1, 2020.
Is Granite Devices going to make an official statement on this?

And how much increase should we expect?

Im interesting to know. Thanks

I doubt the increase will be drastic, Also i imagen price increase also comes from modification on the base for newer batch.

There is another HW revision, what has changed?

There is not a new hw revision.
