Consoles are worth it as much as you use them. If PS exclusives are your cup of tea and you plan to play other games besides the exclusives on the PS5, then go for it. PS exclusives are coming between 6 months to 2 years to the PC, so it's up to you if you think waiting makes sense.

But, if I am honest, I would not buy an overpriced console just for two or three games. I would only buy it if I plan to invest on multi-platform games too (which is my case).
