Malthael's Return in Diablo IV?

It is known in lore that after angels die, they are reborn.

In the Diablo IV trailer, we see a Horadrim man (presumed to be Lorath Nahr) talking to a grave which is assumed to belong the grave to Tyrael, who possibly died after the events of Diablo III.

Considering Malthael was killed by the Nephalem and Tyrael switched aspect, from Justice to Wisdom, along with his (so far) unconfirmed death, How would these archangels return?

Would Malthael become the new Archangel of Justice? Would he be reborn acknowledging the importance of humans in the greater scheme of things? If Tyrael really died, would he be reborn as his compassionate self, or something worse?

Too many questions; I just want your ideas/theories.

Don’t count on it he did not just die, he was obliterated.

You mean like Lucion? It’s a shame if that’s true.

According to the Diablo IV website:

“As darkness returns to Sanctuary, a brave few dare to face this threat. But what fate awaits them in a land forsaken by hope, valor, wisdom, and justice?”

Just keeping my hopes up but honestly, it could mean anything.

Tyr, is a master tactician, not a soldier. There place in history, would require devotion from a deity, to accomplish what you attest. There service, is not in question.

As such, they have stated that, they would not remain a lost soul, (though that accurately portrays Tyr). If they had a way out of it, they acknowledge there own tactics would make them the equal of the prime evil.

They where a master of the light, if you want to help, try hanging a lantern. The way a map domain is formed, there is no way to invent a maps location. it must already exist, meaning the correct answer already exists.
