Hall effect joysticks would be great. The rest I don’t really count; obviously, better performance/bigger screen would be an incremental improvement, but I don’t need it. The OLED screen is plenty big enough.

I (personally) would never use detachable controllers and wouldn’t want more moving parts that could break. Haptics and adaptive triggers I don’t care about improving. For sound, I prefer headphones for when I want “good” sound, too, so that wouldn’t make a difference for me.

Even hall effect joysticks are only going to matter to me if my current joysticks break or develop play.

I really do think the current OLED is amazing.
