In the demo I saw, the player had to infiltrate a renegade camp. He needed a disguise to pass as a mercenary in order to do so. To that end, you had to go to the Sanctuary, a hub that was created for you by your father. The Sanctuary can be called up by what Molyneux called an "innovation to the start button."

Normally the start button just summons a 2D menu with options, or things like armory options. In Fable III, you still have the same functionality in the form of an armory and a dressing room which provides a visual representation of those traditionally 2D menus. It also has a butler voiced by John Cleese. He provides some humor and comments on whatever you choose in the armory or the dressing room. In this case, selecting the Mercenary Outfit elicited a comment about how that outfit is great for acting like a mercenary. Truly invaluable feedback. Good thing it’s John Cleese who says it.

In Fable II, only 20% of players changed their weapons in the entire game, unless they were kind of forced to change their weapon. For example, when a chest with a weapon in it was put in their path, they might change their weapon. Molyneux said that that really pisses him off and that it’s rubbish design that only 20% of people bothered to change their weaponry. That in conjunction with the fact they were bored of making new weapons. So they decided to let you the player craft your own weapons.

Fable III lets you craft your own unique weapon by not only choosing your own preferred design but also by the way you play the game. If you mash the attack button all the time, your weapon will evolve differently than when you use charge attacks, block a lot or when you time your attacks. Molyneux hates the idea that in the end game your weapon would be worth less than the most expensive weapon you can buy. It should be worth more! You can swap weapons and magic on the fly in combat, which also affects the way your weapons evolve. Although no concrete details were given about exactly how this weapon evolution process works, you should get the general idea.

Storywise, it should be better than Fable and Fable II since Molyneux thinks those games lacked story. Becoming king is all about making promises in order to gain the needed support. But when you are king, the way you handle those promises will result in different situations. There was something spoiler-ish things he couldn’t talk about to that effect, but he gave me a “pffff” face when I asked him if it was something that would carry over to Fable IV.

Finally, being king won’t be any type of god sim or anything. It will still feel like Fable so it will involve you running around and killing things when you are not screwing with spouses or manhandling your offspring.
