I think we should have it, but not yet. Not for at least a few more years. Latin America and Africa and some other regions really need to get proper treatment, to level off the game. Ideally with some big improvements to the whole colonization process (you can see my signature). But I would really like to see an EU5 where we have pops, dynamic trade flows, better ai, more consequential geography, more opportunities for "big picture" things like institutions and ages, among other things.
