You know you want a ps5, then just go for it. I own both consoles and both of them are amazing. So it can only comes down to what games you want to play, and since you want to play those ps5 exclusives, then go for the ps5. The Xb one can still last you another year at least before they fully stop making new games for it and if you buy the xb series in the future, any previous xb games can be play on it
