There are 6 classes selectable: Fighter, Cleric, Mage, Elf (Heretic), Marine (Doom's one), The Hero (from Witchaven). Each has 8 weapons.
7th is Heresiarch - this one is NOT selectable; There's Kill The Heresiarch game mode, similar to King of The Hill; there one of the players transform to Hereisarch class until death, his killer takes his place. Heresiarch has 5 weapons (he does not need more, believe me
Well, 8th is Pig with 1 single weapon.
I really hope we'll make a new release before New Year.
