I also haven't heard any new voice bits. Still my only two are "haaa!" and "Uahh!" during my rapier fights. No change since I started.
Which is kinda sad, because I know from GW2 how much atmosphere proper battle sounds can add when you hear people grunt, yell, scream in pain or in excitement instead of a turn-based "Ouch", "Oh.", "Ugh" sort of thing every 100 times you get hit.

But then, I have the typical rough Plainsfolk voice (by accident I picked the right one and learned later Plainsfolk and Dunesfolk males sound different according to the voiced cutscenes) and after those years I can imagine it's near impossible to recreate those.
