Perks: Rumored to be in Skyrim. I may have understood it wrong.
Perks aren't a rumor, they're totally confirmed. They're associated with skills. There may be exceptions to that, but that's the general trend at least; the article talked like they were all like that.
10 races to choose from (Holy crap thats a lot of races)
No it's not. That's the same as every other Elder Scrolls game.
So far, I like everything we've heard about it. I just hope all that actually makes it in and is implemented well.
Things that are unconfirmed, but I hope are in:
Spears. I am not alone in this, just about everyone I've talked to really wants spears and other polearms back in Elder Scrolls.
Levitation. Not as big a deal as spears, but moving in a 3d plane is something people would like to see back in the game. It was out of Oblivion due to the cities ont being open, so hopefully it's back in now.
Climb. This was taken out back in Morrowind, but considering the mountainous nature of Skyrim, it would make sense to do it now. Since they're having less skills, it would not be illogical to combine climb, athletics, and acrobatics, and thus have a general locomotion skill.
Snow Whales. These were never in Elder Scrolls o my knowledge, but they're in some of the old books, and they're a very interesting creature that I'd like to interact with. Of course, they were designed by Kirkbride, and the current higher-ups at Bethesda seem to rather dislike his stuff, despite (or possibly because of) its popularity amongst fans.
