Well, I suppose you'll still be able to be a "grand duke" by holding more than one duchy title, as in CK2. As for the Marquis title... maybe if you're a count and your capital is at the realm's border, your liege can designate your land as a March? And then that changes your title name (though not your tier)? Pretty please, Paradox?
That confirms there is no marquis nor grand duke rank, shame! I mean, CK2 added emperor-tier, so you'd think a next installment would add another, but I guess not...
