So how are the Alliance and the Horde going to cooperate now?
One of the most if not the most likely candidates for leading the Alliance is now King Greymane (being a king in the old alliance and how important Blizzard seems to be making him), and Sylvannas is now the Warchief.
And I don't think that there's anyone in the Alliance who could possibly hate that more than Greymane. Greymane already hates the Horde from the old wars. Sylvannas used the Plague against the Worgen while invading Gilneas (the Gilneans weren't even part of the Alliance when they were attacked), polluting the city and driving the worgen out of their home. Sylvannas personally killed Greymane's son in front of him.
And as far as Greymane is concerned, the Horde got his friend Varian killed by abandoning the Alliance. He certainly didn't seem happy about anything going on in the cinematics.

Im 99% sure Anduin is the new king and leader of the Alliance by right of succession.
Yes, Anduin is the new human faction leader. But it doesn't necessarily mean that he'll lead the Alliance, from what I know.
