The creators, and everybody who worked on this mod, have lives of their own, and they release they mod for free. It's not that they no longer have incentive to work on the mod, but I can imagine it's hard to clock in a lot of work on it, especially since it's in such good shape. There are still bugs in the game, but one has to consider the history of releases and bugfixes, and look at the product we have now relative to earlier versions. I do hope for a future release, but all we can do is wait for word from the modders, and until then, enjoy the game. I'm pretty darn satisfied with the near-finished game we got from amateur (no offense intended!) developers.
TL;DR for the OP: maybe, but we can pray.
