I've got my books and I <3 them. Some crazy changes that I think will turn out to be pretty darn sexy! Of note:

• New Races: Dragonborn, Eladrin, Tiefling
• Removal of Half-Orc and Gnome
• New Class: Warlord
• Removal of: Barbarian, Bard, Druid, and Sorcerer
• Healing Surges
• Powers for all
• Multi-Classing as feats rather than outright class changes
• Major changes to attribute increases
• Diagonal movement is 1 square rather than 1.5!
• and a whole lot more...*drool*
