I do hope they leave the HUD to be off, even better, since I like the HUD on, and the the compass, but to turn the quest locators off. Why we can't have this? Guess just lazy programming. But yeah I am looking forward to the better AI, because I tried to be a "spy" or "thief" to see what the AI does and found it very boring, since all they did was just walk A to B to C. I hope this is not the case for Skyrim.
I think they said that HUD was completely removed from the game. I dunno how they will handle it.
