Err, what? Of course the sources for 3.X exist. It's not developed because everybody here tells me "go away, we have no interest in it". That's a difference. Again, I've no problem if people prefer AROS - that's a choice everybody can make - but don't tell me that there are no sources for 3.X. There most certainly are, and they would be most certainly be used if there would be interest in a - albeit closed source, paid - development.
Err, what? From your answer is unclear (at best) who is interested and who is not. I suppose users are interested for quite a long time. They proved it by buying OS3.5/3.9/AmigaForever/on forums, many many times. Parties who are NOT interested are copyright owners and developers (yes developers too, if we agree that there is the way how to reach the license and sources).
