We don't have details about their plans, things don't seem to be going well. I heard about the HDAC swap plan but didn't see an update on this plan. The price of HDAC is decreasing day by day.
You are right, the coin price is based on the activity they perform and how far they are actively providing updates. Hdac team should always recruit one developer in order to solve the issues quickly and it will surely help them to gain trust in the market. If they are dragging things like this definitely they will loose more trust in the market.
