I can see a future where the game could increase in price as it becomes more popular, (which I believe it will). I also see where it could someday be removed from game pass.

Does anybody have any insight or thoughts on this?

No. It's in early access still and doesn't get consistent regular updates. It's a work in progress game thats being treated like a polished product ready for DLC
