When it's done! ;-)
As a beta tester I can say that we keep finding bugs, and the excellent team at ETC keeps fixing them. Now over x-mas holidays it have been standing still on the testing part but I'm sure it will start soon when people is back from holidays.
And as a Beta tester I would say that you want to wait... you don't want the builds that are now. It's a lot big changes in the software and it's allot that need to be tested and fixed. but they hoped for the end of 2017 so I think it's close.
