Some it it we already know so I avoided posting some of the info for that reason.
-they talk about dynamic snow that's you'll see falling on the terrain and accumulate (yes, they said accumulate)
-dragons are scary, the earth trembles when they land
-it has a lot of dynamic scenery elements: moving plant life (probably in the wind lol), flowers you can pick, animals running around, rapid waters with fish jumping out of them
-they praise the immersion that Beth achieved through stuff like AI, graphics, dynamic environments, interface
-map the size of Cyrodiil with 5, and I quote, "really big" citties, 24-25 smaller settlements and about 120 dungeons.
-they refer to wolves as "skeevers", they also mention "dragon priests"
-combat is way more tactical
-cities will be more alive thanks to the AI
-they talk about while talking to people a dragon might attack and you'll see them running for cover and guards running to their posts
Article also includes a new image with one dragon at the top of a pillar (not the one from the GI article!). My personal opinion: dragons look effing awesome!
EDIT
-they talk about potion/poison making and enchanting (crafting basically) as if you'll only be able to do it in towns.
-they talk about combat and they say combine everything and experiment to see it's results (they speak of this in general terms, not referring to spell combos specifically so don't get your hopes up just yet), they also mention equipping the same spell twice and using both hands at the same time to cast it.
-the unique moves of each weapon and unique special FX of each spell make combat spectacular and vibrant
-game world adapts to your playing style
There's also a pretty awesome artwork of a viking dude standing on top of a rock with a weapon in each hand (dagger and sword) looking very menacing. It looks like he's standing next to a mammoth or at least something that has two horns, the creature can't be seen only the horn things and it looks like it's fallen judgind by the position of the horns/tusks as if the dude killed it (he looks pretty roughed up).
