Well you can of course wait until the team has retired from work.
I mean, my recent experience is that quite a lot of people coming/returning here still care about their old pets.
When I got here last year I asked about several projects unheard of for years...
-BWO had been declared dead by former team members, but Raven and BlackDove said they wanted to finish it at some future point.
-Teeth of the Tiger was inactive for 5 years. Then BengalTiger returned and stated he had plans to finish it.
-MindGames had been inactive for a similar amount of time but Karajorma stated he preferred to keep story and assets private so that it can be finished at some future point.
Of course you can say "aside saying that they don't leave their brainchilds to die nothing happened", but after all it is their hobby, so they can work on it as long as they please (though releasing would be good of course
). When I asked about TI it had not received attention for a long time as well, but there were several interested people and I still hope it'll get released some day.
TL;DR as long it is not cancelled, there's still hope.
