I have the feeling the intros we saw in the stream were just for the demo or whatever version of the game the people there were playing. I do hope they bring decent intros back and not those "fight introductions".

Also, I'm pretty sure they never changed the sounds of monsters unless they got reworked (3rd gen Rathalos, Rathian and Diablos) or new voice clips when the monsters got new attacks.
