I would only buy consoles after they had been out a few years, mid to late lifetime of the console, the primary benefit was it's nice to have in the living room instead of on a desk. Most of the games I bought were used or on sale. All of my purchases have been long tail distribution of a system. If a console goes digital only I won't buy the console. Most of my games are on pc now anyway, none of the modern games are way better than older ones, the only reason to keep up with the times is for community and discussion around the current events of the game, but I prefered single player games in the first place. But even now I have a backlog I can never finish in my lifetime, most of which are considered good.

So long story short, if Sony goes digital only, I will go back to retro and pc and I won't feel like I'm missing out that much if at all.

I just have a desktop computer plugged into the TV in the living room.

The primary benefit of consoles is a mix of price (at least in theory) and exclusives, which Sony still does.
