I really hope there'll be another version, but I don't know if it'll affect me that much - 3.4.3 is fine, no real bugs, and the DevTeam's updates tend towards the minor. I think it's fair to say it might be finished.
Along a similar line, there's no telling if/when ADOM's creator will get around to finishing/releasing JADE. I'll be happy if it ever comes out, but honestly what's out there is fine for me.
