Well in my case, I recently won a 4k TV from my company, when setting it up, I realized I didnt have anything other than maybe a high end pc that would take advantage of the higher resolution... so when I heard about ps4 pro, I was like yaay, a working 4k console,

Square Enix clearly shows support for either up-scaling to 4k, or high frame rates, Deus Ex, Tomb Raider, and Final Fantasy 15 will be supported, so its possible, maybe not a graphical update so to speak, compared to a decent pc (I remember Yoshi P was mentioning how graphics were not a factor in any of the versions of the game, when ps4 ver. was announced), simply takes a bit of deduction to realize Square Enix is really hooked on this 4K, and wants to bring it across all Their Titles (Final Fantasy VII 4k ... woot woot!)

Look chances are we probably wont know anything until the developers tell us, and this is all speculation... but its strange for this title to be any different than the other newly released AAA titles
