That was with the old pipelines. Now they have new pipelines, which will definitely get the content up super fast.

If we pretend that from now on there will never, ever be a delay (ha!), and they can add all stuff originally planned for 3.0 in a weekend (ha!) it'll mean professions will be integrated up to autumn 2018, the first 'jump to another system' will be done in spring/summer 2019, with the alpha finishing somewhere late 2020. Add a year for beta and we're looking at a 2022 full release, provided there are no delays. Which they dont have the funding for, so let me look into my crystall ball again:
1) They release a buggy and gimped 3.0 around gamescon.
2) They show amazing and cool vids at gamescon.
3) In between they strongly hint at a MVP release.
4) Followed by more cool vids.
5) Shipsale.
6) 3.x will be the MVP and go live in 2018. Fans will herald it as the perfect game they always backed, reviewers will kill it. The promised 100 systems never arrive, as do most of the stretch goals.
