In the recent WotC_Shoe statements about leaderless parties, he lists "Warlord, a Paladin, a Fighter, a Cleric, a Rogue, and a Wizard" in one party and "Fighter, wizard, rogue, warlock, and ranger" in the other party.
So, unless the playtesters are using and reporting on classes not in the PHB, we know there are 8 classes in the PHB just from this one report.
Cleric
Fighter
Paladin
Ranger
Rogue
Warlock
Warlord
Wizard
Whether WotC kept a class or two (or even a race or two) carefully hidden until the unveiling of the books, we just don't know, but we do have enough reason to believe these 8 are in.
