So, as I'm sure most of you have heard by now, it seems that Anduin is killed in patch 5.1, leading to some confusion about the Two Princes quest since it's been assumed that "two princes" refers to Wrathion and Anduin. If Anduin really is killed, then perhaps the title refers to the real prince of the Black Dragonflight: Deathwing's only remaining offspring, Sabellian.
Now, I'm sure many of you are thinking "Wrathion's Deathwing's son too, he says so all the time!". He isn't really. Wrathion was just recently hatched, the son of a broodmother named Nyxondra, while Sintharia(aka Sinestra)was the only consort to survive Deathwing's matings after the Aspect went mad. So while not truly Deathwing's son, Wrathion has been using the title symbolically to state that he is the heir of the Black Dragonflight. Unbeknownst to him, Deathwing's direct offspring Sabellian and his black dragon forces are still in Outland, as stated by Blizzard. This seems to me like the setup of a very interesting family reunion.
What are your thoughts on this possibility?
EDIT: Okay, seems I was wrong about Wrathion not being Deathwing's direct son, but still, I find the following things very interesting:
1. Blizzard has specifically stated that Wration doesn't know about Sabellian.
2. Sabellian is noticeably much less hostile than other black dragons towards non-black dragonkin, as seen how he treats the player and Rexxar (while somewhat rude, he isn't openly hostile and shows no intent to actually attack). It is possible that due to his extended period away from Azeroth (and the Old Gods) that he no longer hears the maddening whispers that plague the rest of his corrupted flight.
3. Sabellian is much older and more powerful than Wrathion, and used to be Deathwing's lieutenant. If anything, he's the true heir to the black Dragonflight.
I'm just saying that IF it really is true that Anduin's dead, these two princes coming in contact instead would be very interesting.
