I have to agree with Bluedevil, but can also share my disappointment at the slow pace of the Birds of Prey development process!
Game development by WWW does go forward though, however at a pace closer to what we might expect from sim hobbyist, rather than by a full-fledged software developer, but then that's to be expected since the sim is being created by part-time "employees" working in their spare time.
Having been on the WWW forum forever, I've learned to be patient beyond my usual ability, and to a degree this has put me in good standing for waiting on Knights Over Europe too, of which updates have been far and few between..............it seems to come with the territory!
I truly believe that the team behind BoP want their work to reach the light of day someday, and I still think they carry the passion for their project to see their work through, but when BoP will be done is anybody's guess!
The good thing is that KOE seems to be moving along as announced, and we'll have it to satisfy our great desires for something new in the WWI sim world to experience in the not too distant future!
BoP still exist in a realm beyond guessing when it may arrive, but work does still continue, and I can say this with 100% certainty! B)
