Fully orchestrated soundtrack and voice acting done well-but not for Link. Link does not need to speak, but the rest of the game should have voice acting.
Stronger narrative-TP became a dungeon crawl in the second half of the game
Non-linear progression through dungeons-maybe 3 or so are available at a time?
Set in multiple regions-not desert/lake, I mean like Hyrule/Termina/Holodrum-but obviously not those lands. I think that'll give it a more epic feel-epics are supposed to be about great journeys through different lands.
MotionPlus only-push the tech and push the software to be as refreshing as it can be.
EDIT: More "set piece" moments outside of dungeons-like battles, bosses-stuff like the horse combat against King Bulibin (I think?), Hidden Village shoot out, wagon escort in TP and the time specific events in MM.
More connection and importance attached to individuals in the story.
