PSVR2 controllers are touch sensitive. Not sure about pressure sensitive, but resting your fingers on the button is used in many games. It also detects your other fingers, closed or open palm.
As for features that may never return:
Instant on, no rest mode bullshit (pita with regular power interruptions)
CD player functionality
Card reader
A/V connection options (separate sound out is still very useful)
Ad free UI
No faff local multiplayer (as in no profile bs, press X to join without signing in)
Multiple save slots are quickly disappearing, need multiple profiles now for different concurrent playthroughs.
Cheat codes
Included extras on the disc (behind the scenes footage etc)
Instruction manual / maps etc.
