Well, if you've read the book, you know Percy's definetly going to play a major role... he's part of Hera's plan to form the two camp alliance, and he'll most likely be one of the seven. It's already been revealed that the seven demigods will each have to battle a giant, most likely with their godly parent. We already know Encaledus is an "Anti Athena", so maybe Annabeth will also be part of the seven. :)
