I was heavily leaning towards getting the series X before getting a PS5, but with the PS5 having more exclusives that I actually want to play, the ability to run any PS4 or even most PS4 games is making me reconsider. I'm hoping it will enhance the PS4 games, in which case I'd just get an external SSD for my One X and wait a year before buying the series X since I don't plan on buying both at launch, but I definitely want to get one of them at launch and will wait to buy thee other one until something comes out that I want and can't buy on the other one. The new fable is the only game on series x I want at the moment and hopefully that also comes to the one x.
