Thanks for the heads up. Some hopefully not too wild predictions on which of those Bethesda has covered:
1. More artifacts, greater variety of clothes, weapons, armor, and other items.
2. More joinable guilds/factions.
3. Greater variety in voice acting.
4. Better combat.
5. Better character customisation.
6. Werewolves and dragons.
7. More variation in dungeons/caves/ruins.
8. Better crime/stealth/detection system.
9. Full screen map.
These seem like fairly safe bets to me.
Less likely, but still somewhat plausible, to my mind:
1. Reenchanting items.
2. Item crafting (at least maybe in the Bloodmoon form, where you bring raw materials to someone else, who creates the item for you).
Unsure about the training restrictions - I think that depends on how the levelling and skills systems work.
Aside from predictions, I'm pleased about the heads up, because I tend to agree that those things needed to be improved. The only things missing which were important to my mind were better AI, better dialogue, and better conversation mechanics. Hopefully we get some news about all of these in the Feb GI!
