Personally I believe we are seeing Diablo in that video, there has never been a doubt in my mind. The general face structure and color scheme suggests nothing other than him - and even if other evils appear in this one, they're not going to make a Diablo game that doesn't have him in it at all.
Secondly it is a great representation of evil to me, much more intimidating and demonic than previous versions (humanoid, cartoony dragon-like thing). The cinematics are beautiful and the gameplay looks exciting to me. I'm pretty curious about what class will take the place of a Paladin though, I like playing knight type characters.
Now I can't help but wonder, could Tyrael actually be Belial? I mean he's connected to many aspects of the story and I imagine the lord of lies could make himself appear to be angellic. Then consider the story so far - perhaps the war in Hell was just a distraction, all the while the Prime Evils were still in control and were attempting to corrupt the Worldstone the entire time. Now that they have, and their souls have been put back in Hell, they'd be free to take all their armies and crush Sanctuary. As for Azmodan I don't even remember what he's the lord of, but I'm sure he'll have something up his sleeve as well.
