In case you don't want to watch, some highlights of what Tim Willits says:

-Multiplayer will be a big part of game (not just tacked on)
-Not ready to unveil multiplayer until it's ready
-Rage is not an RPG, no character stats
-id Tech 5 designed to be cross platform from bottom-up
-Focus on making game fun, not tedious (monitoring quests)
-Various weapons but also various ammo for each weapon
-Weapons/vehicles are upgradeable, persist with you through entire game
-Rage due for release "sometime next year" on PC/Xbox360/PS3

Not sure how much of that is new info or not. None of the video looks new, though.
