Probably all the stuff they use studios for (ie running around in a 3D space) becoming commonplace.
Not that it changes much for the classic gaming stream since you're just sitting down, but it'd allow new types of avatar using streamers to do new things.
As far as stuff like Hololive, probably when new hardware (ie the Nvidia 6000 gen) becomes common, I can imagine more powerful computers and rooms devoted to computers where you can sit with other watchers and enjoy the stream together.
Think VR Chat, but with Metaverse concept but actually good avatars.
I dunno how you'd sanitize it so people aren't constantly bothering one another, but I've never seen VRchat players be really obnoxious but maybe I'm lucky.

Literally nothing.

Probably a way to make concerts and in person events more immersive.
Perhaps some sort of AR implementation would be the next logical step.
