Factions... So many choices.

Right. At the end of Warcraft III, there were four factions. The Alliance compromised of Humans, Dwarves and remnant High Elves while the Horde with Orcs, Taurens and Trolls of the Darkspear Tribe. The Sentinels were an army of Night Elves while the Scourge were made up of undead creatures of all shapes and sizes.

At the end of Warcraft III: The Frozen Throne, the High Elves left the Alliance and teamed up with Illidan and his Naga forces led by the Sea Witch Lady Vashj. These elves renamed themselves the Blood Elves or Sin'dorei. So that means only Dwarves and Humans remained in the Alliance. The remaining factions remained unchanged.
The World of Warcraft presented us with two factions: the Alliance and the Horde. The Alliance were made up of the Humans, Dwarves and recently returned Gnomes. The Night Elves also joined up with the Alliance in lieu of their battle against the forces of the Burning Legion. The Horde compromised of the same three races before with the addition of the Undead Forsaken, a splinter group from the Scourge. This decision by Blizzard was a weird one as the Forsaken really has no place in the new "spiritual" and shaministic Horde. But it gets even weirder...

The Burning Crusade presented us with the Draenei on the Alliance side with a burning hatred for the Orcs who massacred them under the spell of the Legion and destroyed their world of Draenor. The Blood Elves surprisingly enough joined up with the Alliance. What bites me is why would the shamanistic Horde allow the crazed and magic addicted elves membership in the first place?

So... The Big Question. What's gonna happen after World of Warcraft? My answer... I don't know. My I'm going to speculate anyways. I shall break down the different factions:

The Alliance: would still have the humans (duh...), the Dwarves and the Gnomes. The Draenei would stay I imagine as they make a good replacement for the departed High Elves and their magic and technology would suit well in the highly magic dependent and technology driven Alliance. The Sentinels will leave the Alliance forming...

The Sentinels: In a word (or two) - Night Elves. A faction of these mysterious Elune worshiping folk coupled with the children of Cenaurius. I would love to see the Pandaren send a small emissary of warriors to aid the Night Elves. I shall get into that later but for now the Sentinels would compromise of these three races.

The Horde: Orcs, Tauren and Trolls... Oh my. Well what do you expect? No changes here save booting both Elves and Forsaken out.

The Scourge: From his Throne on Icecrown, the Lich King and his vast legions of undead will make their inevitable return. I would add the Vry'kul into their ranks just for flavor.

Now comes the hard part. The formation of new factions. What races do we have left? Blood Elves, the Forsaken, Naga, Goblins, and many more. My problem is which races to team up to make a new faction. On one hand, we could have the Illidari... Blood Elves, Naga and Broken Draenei. But on the other we could give the Naga their own faction and have the Blood Elves pair up with the Forsaken. I'm leaning towards the later. I guess I'll have to marinate on that one.

Questions, questions that need answering.
