We still don`t know that, right?
I'm guessing Ner'zhul, even though his name I don't think has ever been brought up today.
Nope, we don't know.
I'm hoping Blizzard sticks with it this time instead of caving and telling us. It's like people want to know the end of a movie after a trailer comes out or the end of the third book of a trilogy before they read the first.
We didn't know Kil'jaden was showing up in BC, we didn't know Kel'thuzad would wrap up Classic. Just go on the ride and see how the story unfolds.
"There is good and evil in this world; we must find the black and white in the gray."
From a know nothing perspective? Garrosh.
From a bit of close reading? Grom.
In actuality? Apparently not an Orc Chieftain.
We will most likely fight against garrosh and his iron horde, Gul'dan will continue to attempt bringing Burning Legion to the world. It will be our job to stop both of them, but as we all can predict, we will fail stoping Gul'dan, and Burning legion will be here sooner or later (for the next expansion). So, Siege of Orgrimmar was "merely a setback" basicly.
Edit: Of course, everything I said is pure speculations.
With all the crap people gave them when they announced Garrosh at last Blizzcon, you were not seriously thinking they would reveal it ahead of time this time?
Garrosh isn't a boss in the expansion. That was stated multiple times. He's just a story character.
When I think about it, Chris Metzen gave a hint during the WoW: What's Next panel to who it would be by saying "he's not just another demon."
I'm guessing Wrathion will be the guy we kill in the final raid. But I don't think there will be a true penultimate villain of this Expansion.
If I had to guess at this very early stage how things go down, it'd be like this...
5.5 - Something wrapping up existing open storylines from MoP.
6.0 - Garrosh's Trial, Bronze Dragonflight nonsense hinting at timeline modifications.
6.0A - The Dark Portal turns red and Iron Orcs start streaming out of it. We beat them, go through the portal to Draenor. Some crazy shit happens, and we kill a number of chieftans between leveling and the two raids.
6.1 - Things are looking grim for the Iron Horde. Grom, beliving Garrosh to be the cause of this failure, ends up killing his own son and taking complete control of the Iron Horde for himself.
6.2 - Raid against Grom.
6.3 - In the chaos following the death of Grom, Wrathion makes his move. Revealing that he was the one who planned Garrosh's escape into history. He needed an army to destroy the Legion, and Garrosh was going to make it for him.
6.4 - Raid against Wrathion.
6.5 - The Iron Horde, all but a memory now, is met by Gul'dan. Offering them one last chance to conquer Azeroth. He has been contacted by demons from another timeline, and they are willing to arrange a meeting to discuss the Orcs joining the Burning Legion...
In the end, at least for the Orcs, the future refused to change. They join with our Burning Legion and assist them in launching the Invasion of Azeroth that sets up 7.0.
I predict, someone behind the scenes. And I can bet that they wont spoil it this time, like they did with MoP. One thing's for sure, its not Garrosh. Hes actually going to be delt with early on, apperantly.
It's going to depend on how the expansion plays out. As it is, based on the "Warlord's" current history, I'd say Gul'Dan, because he seems to be the most evil of the bunch and definitely had the most impact on current WoW events (sold the Orcs to the Burning Legion, opened the Dark Portal, practically destroyed Draenor and turned it into Outland, created the first iteration of Death Knight, etc.).
As a twist, I think Durotan should become the main bad guy. Just think, Thrall, hero of the Horde, hell, Hero of Azeroth, who stood with the Dragon Aspects to fight Deathwing, who led the Earthen Ring against the forces that sought to tear Azeroth apart, who founded and formed a more noble, honorable Horde and sought peace with their enemies, finally meets his deceased father and they end up on opposing sides of whatever war the expansion brings.
I bet ya Burning Legion is the ultimate baddy. Its the only way I can think of the final raid leading into the next xpack like they said.

My God, what a horrible creation. People seeing what they want? Thank God they tried to shy away from that. I know it pisses me off when I'm in an heroic raid, yet in the back of my head all I can think is 'some casual player is playing a heroic dungeon and not wiping.' -Vodkarn
Nope. he's going to come out of a hat at some point. I see us disbanding the iron horde and an ogre invasion hitting us in the dick, followed by a Draenic dragon to the eyes.
