As stated before me, I would evaluate the console side before concluding anything.
There are still many who cherish the game, and would continue to support future progression. Even if it was offered as a paid DLC, (obviously depending on what the contents included), I think you would still find success.
Question is, have you talked to Iron Galaxy? Would they even be willing to step back up and continue their efforts? What happened wasn't TFP's fault, so I don't see why there would be any bad blood between you two.
Honestly, I would expect to see a version eventually after the PC is officially released. Especially with next Gen consoles. While that is depressing in itself, I'm still grateful for the version I own today. (Of course just a little envy of the new POI's and painting system still lol).
If at the least, would you be able to at the least work on the issues that plague consoles? Especially on the Xbox side? Just because I'm on PS4 doesn't mean they should be stuck with a broken game.
Still, at least we finally have some form of news regarding the state of things. Speculation's will spew forth, so who knows what to maybe see in the future.
But for now, I still got some mining to do for my future builds lol.
