I'm pretty sure the reason you can't block with duel-wields is because there isn't enough buttons on the controllers. I sort of guessed what button would be used for what from what Oblivion was like and what Todd said: Triggers control the hands (like what Todd said), "A" button to interact, "B" button to open the menu thing, "X" to draw, hostler weapons/spells, "Y" to jump, down on the right thumbstick to sneak, down on the left thumbstick to switch between first and third person, one of the bumpers to pick up stuff, and the other bumper might be for using the Dragon Shouts (since I can't think of how else one would use the shouts). Since all of the buttons are being used, they couldn't add a block button (when you don't have a shield equipped) even if they wanted to.
