Well, er.. yes, my wife pre-ordered it from buy.com and it arrived Wednesday. Unfortunately, I can't tell you about it until Christmas.
Okay, I did flip through it. 75% of it is the prestige classes (with sample character). The core classes seem interesting. I wasn't pleased with the hexblade. It has abilities I was not expecting based on the names: at 3rd level it gains an ability where it can ignore partial results from spells when it makes the same. Like evasion but also works on those fort partial spells.
Exotic Weapon Master is a 3 level prestige class that is a must have for the dwarven urgosh wielders.
There are epic feats in the back. Someone will have to compare them to the epic handbook to see if they've been updated. A small amount of equipment. Some strange weapon style feats: Bear Claw style is something like a feat to improve Axe/Dagger TWF style characters.
But that was just a flip through the book. I'm sure you'd prefer a better read once it's available. I'll check back next month.
