I would like to see a development timeline from the devs.
Understanding that this would all be estimates, this would give us some idea of what priority is being given various goals and objectives.
The production of a timeline is very typical in any type of project management evolution, and this should not be a big deal.
Why do I ask this?
Personally I want a reason to keep playing. I want to be optimistic about the future. Of course if there was a timeline it's definitely a month+ delayed (the whole server stability debacle). But most of us can understand having to push back desired completion dates because of unplanned pain. I want to see that there is a plan to address the various concerns of the community (whether or not we like the 'how' is another subject), and that those concerns have an estimated date attched to them.
