It's very frustrating to see the price drop, but hopefully you can appreciate that development is something that rarely meets a schedule (ask any startup or corporation), especially when an item expected to be doable turns out to be not! If you successfully bottle-up the developer, you'll only realize problems in ability-to-deliver. It's development, not magic -- takes time and the time required is incredibly hard to predict (you've no idea unless you've been there).
This is largely a patience game. Whatever is publicized has to be absolutely certain, futures and uncertainties cannot be mentioned (they may fail to happen) -- only what is certain is safe to mention! The one negative certainty is a popular failed delivery will be held against you!
