noted in the intro that Sony has a 2:1 advantage over the Xbox Series X|S, but it's actually a little worse than that.
I was quite bullish on the Xbox Series S strategy in the early days. On paper, it makes a lot of sense to have a more affordable SKU that can potentially target students, younger gamers, the gift market, and stuff like that. The Xbox Series S makes up a significant chunk of the Xbox Series X|S player base, although we don't know exactly by how much.
I thought it was a good strategy, but unfortunately, it seems to have come at the expense of the more powerful, direct-PS5 competitor Xbox Series X, which increasingly doesn't seem to have the install base developers and, perhaps Microsoft, need it to have. So, for third-party developers, not only is developing for the Xbox Series X|S lineup more expensive (having to test and maintain two separate versions), it also comes with poorer margins, since you're obviously going to sell far less on Xbox Series X|S. The "S" version will also showcase games at their worst, which is not something developers would want to do ideally, making it easier for PlayStation to land marketing deals.
