The Dragon Disciple prestige class doesn't get any natural weapons, except for a bite attack that can only be used (3+Cha mod) times per day, and apparently Draconic Bloodline sorcerers in general get a +1 damage per die ability, to make up for their 1st level attack power now doing reduced damage and only (3+Cha mod) times per day. Note, their 1st level attack power is claws. Proof that they hate sorcerers
Hmm, Combat Expertise got altered to work similar to Power Attack. -1 atk for +1 AC, increased by a point at ever 4 BaB. They also got rid of the entire Overhand Chop/Backswing chain of feats. Cleave only takes a standard action to perform for the two adjacent attacks (if miss the 1st, auto-miss second), but it gives a -2 to AC for the maneuver.
Animated Shields work like Dancing Weapons (release, function for four rounds, returns) and had the cost reduced to +2.
It sounds like they're doing something Monte postulated a few years back, where higher bonuses on your weapon allows it to ignore other kinds of DR besides magic. It's +3 for silver/iron, +4 for adamantine, +5 for alignment. Note, they word GMW to not allow it to grant this additional DR penetration.
