Stuff like dreams for werewolves and vampires and returning the ending cutscenes that somehow disappeared after the Oblivion Crisis would be nice. Nothing major is needed, though. Morrowind had just enough cutscenes and they didn't feel unneeded or thrown in. The main series TES games do not require more cutscenes than the ones in Morrowind. The main series TES games are open world RPGs, so cutscenes are hardly needed for much other than what I've mentioned.
You stated that better than I could. That is exactly how I feel about cutscenes in TES.
