So since we need to see other players in the world how they interact with objects, how move in combat, their body animation, that can lead to TPP for Singleplayer after Multiplayer lanch, that would make many people happy, i would happly wait for multiplayer lanch if i know that i will get full TPP for a singleplayer.
I think at some point you will need to decide whether you can accept the game is FPP focused (both gameplay and most cutscenes) and still want to give it a go, or not. The "TPP" posts on reddit don't really have much traction, maybe a few hundred upvotes compared to thousands in popular threads. I seriously doubt that CDPR will change their whole concept for the game, beyond minor extras like a better photo mode...
