Didn't this new 7.2 cinematic just confirm that Sargeras is not on/near Argus? It looked like he's talking to Kil'Jaeden from some distant place.
Maybe this means he'll not be final boss? Could be that Kil'Jaeden will survive the Tomb encounter which I personally would like but not sure if Blizzard is brave enough to repeat same boss in two raids.
What do you guys think? Do you still think Sargeras is gonna be end boss or something different? Could also be that he'll somehow come to Argus in 7.3 but who knows.
