They're on the srd.Dave, if you're interested, I have the PDF of the new classes they're releasing. It was allowed to be downloaded for playtesting, and I don't think it's on the site anymore.
Since that doesn't have the Elemental Wizard, Gladiator and Samurai class I mentioned, no, it isn't. I was referring to Paths of Power, which I wrote. The APG will feature the Witch (a different version than ours), Cavalier, Oracle, Summoner, Inquisitor, and Alchemist.Not sure if you were asking or not LB, but if you were the designer was Jason Bulmahn and the title was Advanced Players Guide.
