PowerShell v6 has reached a significant milestone – the release of the first PowerShell v6 beta version. There have been 18 releases of alpha code since August 2016 when the open source PowerShell v6 project started.
There is no indication of how many beta releases there will be before PowerShell v6 is ready to ship.
