Would be cool to have one or at least some ETA for next big update

At last I've killed all three bosses at once. All quests are done. Is it the end of the game? Is there any sense to continue playing?

Has anyone found how far down and how far to the sides the map goes yet?

I only want 1 sawmill. Yet the game requires 3 to progress. This is lame. I'm a god, right? My world to do with as I wish, right? Gotta build 3 sawmills, because...I don't want to build 3 sawmills. They just sit idle, at least for the moment, anyway. I'll build more later if/when I need them, and right now I don't need them so I don't want to build them. Furthermore, if I do build them, I'd like the option to destroy them. Since I don't want 3, I only want one, so if I build 3...I'd like to remove 2 asap...

Has anyone had time to optimize any mercenary builds yet. I am not good and min maxing and even worse at seeing the big picture when it comes to these things. So any builds or advice you guys got would be appreciated.
