Haha, yes! Suck it Alleria.. the minute i saw Sylvanas with Xal'atath, I knew it.She is going to be the hero against the void.
They will restore her to being loved by all the horde probably by removing her as warchief, but elevating her further into an even bigger hero.
And the nicest bit, is blizzard is going to use her, and not Alleria as the main star against the void - suck it void elves! Death > Void
