In general, the Roll20 devs will tend to talk about a new upgrade when it's far enough along that it can confidently be said how it's going to work and when it will be approximately released. They do not speculate much further than that because in their experience, things are unpredictable and if it is promised something too far in advance and things change or the schedule changes, people get upset. Nevertheless, I'll go ahead and ping a dev to see what can be found out.
