I can safely say that's not the case. Much of what we're doing with CoreOS or Tectonic depends on open source, particularly our open source projects. That's not going away anytime soon.
To your first question: https://github.com/coreos/etcd/milestones
(and the mailing list is pretty useful as well, to keep up on point releases and announcements and such).
I appreciate the roadmaps on individual projects. I am more interested in the CoreOS roadmap.
So far the approach seems to be, work on a special project in secret for a couple months that aims to compete with existing solutions and then hype a partial release of the incomplete project on a Monday.
(etcd dev here. We've got a long roadmap ahead.)
