I don’t see the game getting either of those things.

Duos, you can already do, you just have to take on a rando as a third. They could scale the difficulty down for 2 players, sure, but Elden Ring’s mutiplayer scaling is notoriously terrible, in part because no amount of scaling can account for the lost potential for splitting aggro, in a game where splitting aggro is king.

Voice chat is something that FromSoft has INTENTIONALLY never included in any prior game, despite there being co-op in all of them. Making players coordinate with each other with very limited communication tools is one of FromSoft’s signature design choices. The fast pace of this game compared to prior games makes the lack of communication tools hurt a lot more, for sure, but it’s still very much playable. If you dislike this design choice, you are absolutely free to, but it’s not gonna change.
