I liked medium armor and intervention spells as well, but Im more than happy to lose those options if it means I can have friends and family in Skyim! I know a lot of people are grumpy about marriage but I'm sooo glad they added it. (i have no doubt they will execute the romance part of the game with more maturity than Fable)
Although some nostalgic options may not be there, it sounds to me like Skyrim will blow Oblivion out of the water in terms of immersion with the changes they have made.
Not to mention non-squishy-face people! With tons of customization! Body size, tattoos, scars..
They skirted the were-beast/vampire question, but why would they leave them out? The lore is there and they've been successfully executed in past TES games, so Im not worried about it. It's good to leave some things a mystery :]
I can't wait for this game! (If only they would announce a collectors edition!)
