Firstly, I'd like to welcome you to the forums. Glad to see that you enjoy the game.
Yeah, the devs aren't really on the game anymore, but just a couple days ago we saw them back here, and they said they are willing to make an update (as long as it's community-funded). We just might see an update once more.
Honestly, I'm not entirely sure why they don't give the rights to someone else, I think they're just still be attached to the game. I don't know who they would give/sell the rights to, without the risk of them destroying the integrity of the game (i.e. making it pay-to-win or ruining the diplomacy/timing/whatever).
A wise guy's always right; even when he's wrong he's right
