That's all great news, aside from this...
•Through missions, the game will encourage players to go places they’ve never visited. For instance, a woman might ask you to save her kidnapped offspring and the game will send you to a dungeon you’ve never been before. It’ll then set enemies that are appropriately matched to your strengths and weaknesses.
It sounds like creature/enemy leveling with the player character is still there....and that was a thing I really did not like.

•Your hero will be tasked with walking 7,000 steps to the high retreat of High Hrothgar to get dragon slaying training from a group of mysterious old men that reside there called the Greybeards.
Spoiler Alert, click show to read: 
How is that possible? They say that whoever hears the voice of the Greybeards, dies!


BTW I don't remember any kind of perks in Oblivion...
