I've not done early access games before, and I was a little disappointed that round the corner didn't mean the next day, but on reflection it really didn't seem to be unreasonable to expect it to be a week or two.
Immanent I'd expect to be sooner, with barely enough warning to finish a side quest, but then I've pretty much run a whole run through with a new this last week, just to see how a different approach works.

I know I'm in the minority here, but from where I sit they've given me all the heads-up I'd expect from a working team, and I appreciate it.
