The most recent Diablo 4 cinematic trailer from Blizzard showcases Inarius looking down Lilith and armies on both sides. While the scene does not mention Tyrael's involvement directly, his involvement in the creation of Horadrim and his involvement with the various Paladins of Sanctuary suggests that he's involved. Dark and light battle on the battlefield The now-dead D2R Items Tyrael is somewhere between.
It is likely his presence will be perceived through these intermediaries unless circumstances cause him to act. Tyrael still feels the repercussions of destroying his Worldstone at the conclusion of Diablo 2. This mystical object protected Sanctuary from Heaven and Hell and now acts as a protector for the region in its place. Tyrael appears unlikely to lead any further attacks into Hell or take his fight any further than his current position at the Pandemonium Fortress, where he could offer advice as Deckard Cain for those who choose to listen.
Five classes playable in Diablo have been released so far They all are different versions of the previous games. Each installment has introduced something new The possibility is that Tyrael may become an element of the battle that balances the sides, offering players the ability to be transformed into angels or demonic abilities in exchange for duty to Sanctuary. This type of mechanic could easily follow on the multi-tree enhancement that was already revealed for the series.
It's not likely that Blizzard intends to turn Angels or Demons into classes, considering that the series focuses on characters Diablo 2 Resurrected Items trapped between their ways. As a mortal who is caught between Heaven and Hell Tyrael has a unique position in all of Diablo history. He's more likely to play acting as a balancer in the story, or even an impartial voice, rather than a partisan as he once did. Even when he is forced to take the side of his opponent, Tyrael has come to understand what is important to mortals, and that's the way he is likely to participate in the events of Diablo 4.
