I don't have a desire to buy new gaming hardware for quite awhile as I've bought quite a bit lately. I've rarely bought Sony platforms at all, and the XB One X and Switch are all I need for the foreseeable future.
If anything, what I might do is get a new spruced up gaming PC in 2 or 3 years, and just play gamepass stuff on there in addition to new PC games. My desktop was bought in late 2012, and while it's still decent, it's starting to show its age. To me it would make more sense to simply have the powerful all-in-one machine (which would be able to play XB games anyway) rather than the Series X which is basically a lesser gaming PC anyway. I'm also not crazy about that big, rectangular design. Plus my cousin, who's a big Xbox guy, will probably shell out for that anyway so I can just check it out at his place.
I don't completely rule out Series X, but it would probably be 4-5 years down the line for me if anything. May just skip the entire next gen on the home console front and stick with Switch/One X/PC
