They need to be.
Look at the current posts on the subreddit and the forum. Your core player base is simply stopping playing. You might be selling copies but if your core community is splitting or stopping playing then you have a problem.
I think we don't really need answers as to WHEN. Well, at least I don't.
The real question is WHAT. Zac, what are the priorities?
I would think that you can divulge a little information about the things that are already in construction, and say have above 80% chance that they will be in the next few feature updates. We don't "demand deadlines", just want to see where, what direction are you going right now. (not planning to go, but the actual things that are in the "forge" right now, the things that are on the screen of the devs right now, the things they are coding towards at this very moment)
The reason for this is simple. With the last few surprise updates you've done/announced (PP and CQC) you've taken a up very different path to what the most of those who expect any direction were expecting. (according to the posts I've read and in my own opinion)
"something is coming, we are very excited, but can't tell you what or when" sounds like marketing talk for "we're working on something you won't like when it comes out" or "it's not anything we agreed on doing"
