I agree with the observations and comments made by @mbabker and @brian. I also agree with the implications made in the question asked by the OP. The question is, indeed, "loaded" in a way that implies that the responsibility for delivering J! 4 [beta] is all about the development team, somehow, and has nothing to do with the community's involvement in testing things.
Let me also state for the record that I am not well equipped to involve myself in testing alpha versions of anything (esp. if the testing activities involve anything more than download an installation package of something and run it like any "ordinary" person would do). Furthermore, alpha versions are not locked down, in the sense that features are constantly being added, expanded or contracted. The situation is too fluid for me to say that "yeah, it works" only to discover that a few days later, a feature I tested was removed or that a new feature was added. So, for those reasons, I stay clear of testing until the feature set has been locked and we can move into beta testing.
The most important feature that's need, in my opinion, is the ability to seamlessly update from one version of J! to another. This isn't just the case for going from one version of J! 4 to another; it's also important to establish that people will be able to upgrade from J! 3 to J! 4 and I haven't seen any sign of that happening while there's all this arm-wrestling over what should, or should not be, in scope for J! 4.
Also, the
nonsense discussion about all the things that people seem to dislike about the backend design of J! 4—that has mysteriously been marked as "resolved" and yet it continues to go on and on (?)—has been a total turn-off for me. I'm so unimpressed with that discussion that I don't know if I even
want J! 4.
Three years ago, someone asked me at a local JUG meeting, "When do you think J! 4 will be released?" I replied, somewhat off-the-cuff "It won't be
this year, mate." About a year ago, someone else (who is a long-term member of this forum community) suggested that I might like to involve myself in testing J! 4. I answered him in the terms I outlined in the second para. above. Things are just too fluid, too changeable.
If one wanted to bet on the delivery of J! 4 (beta, RC or stable) then I believe the odds would be long. 100-1 for J! 4 [stable] this month (for starters); 5-1 for J! 4 this year. I wouldn't even know when "even money" would be a bookmaker's odds given the running commentary from the punters (incl., perhaps, punters like me).
Your guess is as good as mind but here's what I feel might offer some certainty. Once the J! 4 feature set is locked down and we're not continually dealing with scope creep, J! 3.10 needs to be brought out alongside J! 4 beta.
