There will be only 5 classes at launch(the way they word it in the faq makes it seem like there will be more...)
already one of the original 5 has been replaced with a different class(don't know which) with the witch doctor.
so far we know about the barbarian and witch doctor, and i'm pretty sure they said there were more new classes so its possible another class isnt going to be in the initial game.
my guess:
barbarian, paladin, sorceress, witch doctor, amazon replacement(i think they are replacing a melee class and spell casting class...i guessed they are replacing amazon because?)
