For people really sold on the idea of BC actually mattering this gen because Sony is finally coming up to speed in that area?
I'm very lazy and dont feel like looking but I seem to remember that when you look at the numbers/data, BC matters to a very small percentage of the user base.
Second, for those excited about BC, are you really excited just to play the same games with no innate improvements? That's what Sony's BC strategy needs to include, IMO. They'll need to match or improve upon what Microsoft has done in that arena.
Edit: a bit old (2017) but you get my point:
It was, but many of us have digital games and growing digital libraries, carrying them forward is a big deal to many.
