I think that Nazgrim will be on Garrosh side, maybe as warlord or high warlord, because garrosh valued him, because garrosh made him important.
He may be one of the Siege of Orgrimmar's bosses.
However, i'm possibly wrong, and maybe Nazgrim will fight on our side, and after all, maybe the next warchief will reward him with an higher title, warlord or high warlord.
