Is there any public source or social activity where Grey Heavens announce and keep the publicity informed what they are doing and/or what they plan to do (exspecially with Spiral Knights of course) next?
Something like a special overall forum, Twitter, Twitch streams, Facebook, etc?
Just something where players can keep track of what is going on?
It does not necessarily need to be something where we can leave comments, but a place where we can read and inform ourselves?
The only venue, of which I know, is the Announcements forum.
More seriously, I suspect that Grey Havens likes to under-promise and over-deliver. They don't want to say that they plan an update for 5 months from now, because it might take 10 months. So they keep quiet until the release actually happens. Disclaimer: That's speculation. I don't speak for them.
