There have been changes suggested, so who knows.

various streamers have said its usually a week or so from public test to full release; so unless they find anything major in the testing (and no reason to see they will as nothing major has appeared in streams ive seen) then maybe next week or the week after if we are lucky

Nobody knows. Could be a matter of days, or a few weeks in the worst case.

When they feel it's stable enough to release it. There is no given date.

It all depends on bugs, and what else the devs want to put in.

I wouldn't be surprised if it takes a month to hit the public servers.

Till then I am going to explore various base building ideas.
