I rather enjoyed reading this Sorcerer Essentials article, Rob Heinsoo's enthusiasm for the class is infectious (well, at least to me). One of my favorite things about the article were the new sorcerer powers that have effects that if you are a Chaos Sorcerer allows you to roll a d4, d6, d8, or d10. Its an interesting mechanic that has a nice risk/reward which preserves randomness and player choice. Also, the art was really good IMO:
