Future classes from warcraft 3 lores

[Hubernatl]

As a huge fan of warcraft lores i saw some heroic classes appearing in game like Death Knigh and Demon Hunter
What classes do you think will be implemented in WoW ? I made a little list
Necromancer and Runemaster were supposed to be in the game along side with the DK but they got merged into Death Knight http://www.mmo-champion.com/threads/726876-Some-things-you-didn-t-know-about-WoW here you will find more
Enchanter -If you go in Eastern Plaguelands you will find some NPC's called Scarlet Enchanters which use Arcane bolts to hit http://wowwiki.wikia.com/wiki/Enchanter also there is a wiki page for it
Also as i seen the classes which use composed names are
Sorcerer - Another class which looks like mage but uses dark power can be found along side NPC's
Witch Doctor -Witch Doctor is a class met between Trolls which use the power to heal
Warden - If you used to go to Moonglade you would see a lot of Druids which guard that place and have some special skills -this can be called Wardens
Invoker- Invoker like Necromancer and DK can release a lot of death corpses and fight in the battle with them .Some Invokers can be seen in troll tribes wich use Voodoo power
Archmage -A hero class for mage like Kirin Tor
Shadow Hunter a rogue class like .Vol'jin is a shadow hunter
Dark Ranger-We all know Sylvana's class -A hunter like hero class
I really want to see what is your opinion about feature classes
