Well at least we established the fact that he's not working on the update as of now.
Yes the reality is that dev is sick and he will get back to development when he gets better, but there's more to that reality, he's sick for at least a couple months now, in the same period that he believed he would get healthier and be able to close off the update and ship it, he infact found himself unable to do that.
So, because he isnt providing any specifics in order to establish an idea of his current state compared to his initial fallout, and if I follow the vector which started in a couple month delay, and eventually culminated into an indefinite delay and a hiatus. We have to consider that an important part of this reality (which isnt fully known) could imply:
1. dev found himself stagnant in recovery.
2. his health is getting worse.
3. A more complex chain of events that nobody has an idea of its implications even dev himself.
So the honest reality is everybody hopes the dev can recover as fast as possible and be able to close this chapter out, but nobody knows when that'll happen or if it'll happen, even dev himself uses that same rhetoric.
And that's enough of a warrant to tag this thread as "abandoned", considering this tag isnt inherently permanent either way despite its name..
