I think this is a big part of the storyline, so I'd assume that it's the best shrouded. That being said... I think Diablo's voice is still present in the world.
For instance, I think we'll see Leah struggling with an almost schizophrenic voice in her own head (inspired by terror). Diablo will try to scare her into assuming the black soulstone's power to defeat Azmodan (why she sees the vision).
Diablo will use terror, his tool, to inspire in Leah a fear of Azmodan beyond a fear of possible possession.
Once she assumes the black soulstone the "voice" will become much stronger, and as Leah becomes one with Diablo we'll see perhaps and eclipse of the woman we knew and a rise of the prime evil.
As far as the heads go - I believe the black soulstone represents the powers of the prime evils exiled to sanctuary, and also perhaps the surviving pieces of meph and baal (since they didn't have a stepchild to help them gain some semblance of a foothold). When Diablo takes on his form in Leah he is the single prime evil, his brother's locked within him, serving only as channels for their own power.
Strangely I interpreted it that Azmodan was speaking of Belial rather than Diablo. I feel like Azmodan was talking how Belial, the Lord of Lies, manipulated the Prime Evils, and the two lesser evils, Andariel and Duriel, to their own defeat. Since he is talking to Leah, Cain's new apprentice, he may be hinting at something we have already suggested.
The whole premise of Leah seeing the vision is terror. In the end she breaks down weeping. The vision is meant to tip Leahs fear in favor of Azmodan, thinking that perhaps she can hold the power of the prime evils and use it to strike him down.
Diablo is all about that terror and manipulation. In truth Azmodan is a lesser evil, he's nothing heroes haven't faced before. He's an act1-2 level boss in gaming terms. There is no reason to fear him, unless he gets the black soulstone. :)
PS: Little notes - Seven thrones in the cinematic, seven heads to the evil dragon. But there is only one "red" seat (also looked to be the only empty one, perhaps someone with high def can check the other chairs for occupants).
I also highly doubt Tyrael will be evil in any way, or be an enemy in any way. He's in too deep with us Hoomies to back out. Inarius though? I'd bet a pretty penny Belial is having fun with some lies and perhaps working a little black magic.
