There will be some updates (if only related to the WH sponsored event and the stand they will have there) after the Libusin event at the end of April. So that is certainly less than 3-4 months.
The E3 expo will be mid June, and I'd certainly expect some more firm news about progress/performance/maybe a release date at that point.
Whatever the timescale is though, whipping one's self into a frenzy or sinking into despair because of the presence/absence of some words is unhealthy. The current official release date is "2017", the webstores have '2017 Dec 31' as their placeholder dates, which while unlikely to be 'correct' are probably within 3 months either side of what we will see. (my guess).
I'd love to see it complete and released tomorrow, but I know that is unrealistic, and have plenty of other things (including real learning of the practice of the "knightly arts of sword combat" after the Lichtenaur tradition, and later stabby fun with Giganti and Capo Ferro rapier systems) to occupy myself with while I wait for snippets of news and the eventual game (and replay the Beta many times).
