Unless they have added resources to producing C3 then I believe it will take years to complete.
C2 is an amazing application, but it certainly has a few elements that cause a great deal of frustration. Having just finished my third large c2 project I think my main beef is the primitive IDE.
The main bug bears are Bug Fixing - lack of tools and almost useless breakpoints
Searching through the code is a nightmare.
Also sometimes the code doesn't do what you expect it to do which require strange workarounds.
Anyway I hope they open up C3 to alpha and beta feedback. Soon
