No timelines at all other than "2017". Any business that is successful has a timeline, and just wish we could be more specific. If the goals aren't reached, at least you have an idea of whether we're on track, ahead of time or need to put some extra work in.
We don't like releasing timelines because it encourages quick and shitty code if we are running up against the timeline and need to get things finished. I can tell you that right now we are working on our zerocoin implementation and hoping to have it in the testing phase within the next 3 weeks. Then we will squash the bugs, add to the implementation to make it more exceptional, test again, squash, test, squash, then hopefully move on to release process. My estimate would be at least 2.5 months for all of that (if things go according to plan), but could be longer.
Then after zerocoin the plan is to move on to governance. We haven't studied it hard enough, so I can't give any 'timeline' for you on that.
