From OMG! Ubuntu:
The two day event will feature presentations by the Microsoft team behind the Windows Subsystem for Linux (WSL) feature; the creators of the ‘Pengwin‘ WSL distributions; and (more pertinent to our tastes, perhaps) the Ubuntu on WSL team at Canonical.
The free-but-small WSLConf is scheduled for March of next year, so WSL 2 will probably be generally available. Much easier than staying caught up with the Fast Ring.
I may have to check this out.
