maybe they should try this modus - crowdfound module, deliver it in fairly finished state. Use closed beta instead open one. Keep the price up untill finishing it plus a year or so. Then start attracting new people with sales. Current system, where you pay for full module and it is early access for prolonged period and knowing, that rather sooner than later the price will go down by 25, 50 or even more %, is totaly weird. We get half finished product instead more complete one just because some people want hands on new module asap. In my days, beta testing was internal and external, but rarely open to everybody. Maybe in final stages...
EA is alpha and open beta is just open alpha.
