Not gonna lie, getting to preview the PS6, even in a dream is pretty nice. I read that it's rumored that AMD and Sony have finished finalizing the design for the chip for the PS6 already, and that it may release in 2027 / 2028.
With the release of the PS5 Pro though, they may reconsider given that the sales of the PS5 are lacking compared to the PS4, and that exclusive games for the PS5 don't exist in large numbers. Many games are still made for the PS4 (due to the huge install base) alongside a PS5 version, and developers don't want to give up that easy money, especially when the PS4's easier and cheaper to design graphics for.
