The Demon Hunter has become pretty iconic thanks to Illidan, if we never see it, I'll be surprised. Otherwise there is no reason to not add more classes, the more diversity that can be added the better. Furthermore blizzard should go back to their classes being more diverse, having every class with the same exact kit is pretty dull.
It's like crossing an intersection. There's shit going on all over the place and you don't panic and act like an idiot then do you?
Didn't blizz say they use diablo and wow to test certain classes and see how they would work in each enviroment, and that's how we got monks in wow?
I could imagine a Demon Hunter only as a new specialisation for the Warlock, maybe as a melee tank tree.
Yet, new classes would be nice. Dark Ranger, Demon Hunter, Blademaster, Shadow Hunter, Witch Doctor. Problem is, that are a lot of classes. and we have a lot already. I am not a fan of the balance argument, but it has a point.
I would like to see legendary quests, where you can merge your class into something little different.
Let me take the Blademaster as example, because I am a BM Fanboy.
Lets say Rogues, Warriors, Monks would be eligible for that quest. All are melees, all have some sort of the same attacks. All have a "bladestorm" attack.
So, you get the quest, and go on a journey equal to the legendaryquestline on the live servers. You have to kill some mobs, bring some stuff, collect things. then you get you Sword, or Blade, maybe even an Axe, (Grom, as a Blademaster had one) And when you finished it, you get a transmog set for blademaster (the orbs around the neck (colour changeable?) the Flag (horde/alliance symbol(if alliance is eligible, mountain king could be mirrorclassquest) or guild symbol, and some of your spells change appearance, bladestorm, spinning crane kick and blade flurry would have the visual of the warcraft 3 bladestorm of the blademaster. With it comes a nice title, Blademaster XY.
I am aware, that there needs to be more thinking for other classes so that we can have something for every class.
the most realistic option would really be a transmog set for those hero classes, since it would be the easiest way. At least you can look like the class you want to play. Transmog offers such a solution, so lets hope we get at least some transmog sets.

Individualizing our characters:
So, much hate. Let me remind everyone here that playable Pandaren started out as a joke, and yet here we are with an entire expansion centered around their homeland.
What niche could they fill? Perhaps another class that can use polearms and other two handed weapons. Only have 3 classes that use them, compared to other weapons. Perhaps a cloth tank (a la warlock "tanking")? Perhaps a cloth melee dps?
And to rebuttal the idea that the game already has 11 classes and 34 specs, that are unbalanced. So what? The game was intended to be fun. Raiding and pvp are supposed to be fun. Certain classes being OP are what people recall and reminisce the most about anyway. Rogues and 3minute mages from Vanilla? Lolret? So, screw it we know blizzard does their best to balance classes, but it's impossible.
