From games I am following, I havent seen many games on ps5 that couldnt be possible to on a ps4. I mean, image they update the ps4 for using SSD. the full ps5 library could be played on it. turn off raytracing, mid specs, maybe 720p. But playable
Switch 2 being a updated ps4 level brute force with SSD and DLSS and all these new tech would be more than enough for keeping up with at least XSS in a small screen.
Also, clocked up on a dock and no battery restriction, can be compared to them in large screen.
I just hope is cheap.
