its more powerful than the ps4 pro that is for sure. possibly way more powerful but the ps4 pro right now only cost $399 which is more affordable for most consumers. by the time the xbox one x comes out, the ps4 pro might get a $50 dollars price drop making it even more affordable to consumers. $349 is $150 cheaper than $499.
Just as long as games that are optimized for ps4 pro can runs in smooth 60 fps at 1080p with hdr, i am happy. it might be downscale to 30 fps for original ps4 which is not bad.
sure many or some games on xbox one x might be 4k at smooth 60fps, but i don't mind playing games at 2k (1080p) at 60fps. espeically if it have game(s) that i want, so ps4 pro might be for me. beside i don't have a 4k tv yet either.
