Am i missing something?
Then i'm sure we haven't read the same articles.
Then you weren't looking hard enough. They talked about how the AI works in a couple and how it was a big improvement over Oblivion such as they now hunt for you in the dark when you kill their friends and what not. Then we heard about how your character actually picks flowers, meaning that it will actually pick ingredients for alchemy instead of just hearing the sound and it's in your inventory. We heard about how there is life in the waters this time as the fish were spawning upstream, jumping out of the water. We found out that draugrs use Thu'um in the game. We found out there is a chain lightning spell, a mind destruction spell, a ray of frost spell and there were more but I can't remember. There is even more but I think you get the picture.
Edit: Oh and one of the articles talked about the new stealth system as well, it sounds interesting.
