We got a big texture downgrade back in the day to make it all fit in the very limited PS3 memory and for whatever reason they decided not to keep the higher resolution ones as an option for PC players. Probably because PS3 and PC versions had to look more or less the same. At this point I wouldn't even be surprised anymore if higher resolution textures didn't exist anywhere and they'd have to make them all from "scratch". Squenix also has a very strict - maybe even too strict - memory budget on everything most likely stemming from the PS3 days. All things considered I'd be happy with just a gear and character retextures if we were to get any.
