It doesn't matter what business we're talking about. If you can't afford to pay the costs associated with running it, it's not a viable business. It's pretty fucking simple math.
And no, we're not talking about "to big to fail" business (that SHOULD be allowed to fail, IMHO) we're talking about AI, that thing they keep trying to shove down our throats and that we keep saying we don't want or need.
IMHO, Xbox is a better console than PS this gen. I was a PS guy all the way but I got both XSX and PS5 when they came out and I barely touch my PS5 compared to the Xbox.
To be fair, most of the reasons I prefer the Xbox are just user experience things. The biggest one is that I think the PS5 controller is horrible. The ergonomics are all weird for me (yeah I realize that everyone's hands are different) and the fancy trigger buttons are real cool in the one or two games that make use of them but they're squishy and vague feeling in the other 99% of games. The Xbox controller has better ergonomics, and better feel in the hand with its materials and button feel. Yes, ergonomics and feel preference will vary from person to person but it's worth mentioning since I never had an issue with PS controllers until the PS5.
The other reasons I prefer the Xbox are things like how much better it is for things on your TV that aren't gaming (streaming shows, watching movies, etc.), I think Gamepass is WAY better than the Sony version, it has more exclusives I am interested in, etc.
Anyhow, you do you, but you might look into the Xbox a little before blindly just going with the PS5 on the strength of the older consoles. I was surprised by how much I didn't want to use the PS5. And a little bummed if I'm honest. It was a lot of effort to get one at launch and a lot of money and it mostly just gathers dust.
And to answer your specific question, if you do decide to go with a PS5, just get whatever is available when you are ready to get one. When it comes to tech, there's always something better coming so you can wait forever because they will never say "okay, all done!".
