Its a hard question since I don't have the game yet. I guess I will focus on Ermor as always, but I will also want to play with more nations in Dominions 3, because in Dominions 2 I was playing Ermor in 10/8 MP games at average.
I will definitely try out all of the new nations. Agartha looks like very interesting to me. I will try them first after I've installed the game.
