I think it reasonable to think that currently people are prioritising price. If that option isn't available, they'd then be more concerned about prioritising brand. If you want entry-level next-gen gaming, there's only one option. If you want a £500 console, there are now two to choose from and one has as stronger brand and marketing.
I'm not sure GP is the driving factor. Silent_Buddha never proposed it as one either.
If you can afford a 500+ USD console go to the next point, if you can't there's the XBS-S.
Yes, at least up until relatively recently, if you had to choose between a PS5 and a slightly cheaper in some regions (they were the same until recently in the US) XBS-X do you go for the one with more exclusives and better rated exclusives or the one with less? Do you get the one that most of the people playing online games have or the other one? The one that currently has better brand recognition or the other one?
I think it's less about more people buying PS5's. They were supply constrained for most of this generation anyway. It's more that there would be less Series sales without the S than with the S.
If you can only manage to squeeze in a 250-300 USD console into your budget, then both of the high priced consoles aren't in the running. Doesn't matter if you want a PS5 or an XBS-X, your only choice is the XBS-S and if you don't want it, then you don't buy a console.
Additionally, if you have a PS5 but want to take a dip into the Xbox ecosystem, then the XBS-S might allow you to fit that second console into your budget where an XBS-X might be cost prohibitive for just checking out the exclusives on the other platform. Here, Game Pass could make it more affordable to check out the exclusives, but not everyone wants to basically "rent" titles but would like to own them (digitally) and alternatively they might not really know much about Game Pass or why they'd want to subscribe to a service to play games (not everyone watches Twitch or dives into gaming forums
). And XBS-S would make it easier on the budget to include a few games where with an XBS-X your budget may limit you to just one game.
Alternatively if you couldn't get a PS5 due to supply constraints, but that is
the console that you want to get, you may just opt to save your money for the PS5. However, you may be able to afford an XBS-S to try newer games while still keeping enough money in the bank to buy the PS5 once you see one. There's a few people I know that did this. They all have PS5's now. One of them has sold his XBS-S but the other's have kept theirs just in case they see an Xbox exclusive they want to play. The XBS-S is also handy for some of them with families to let the kids play Minecraft on it while they use the PS5.
