They should scrap the PS3 version.

Yoshi-p said that he going to keep updating the look of FFXIV for the PC version. Which mean a high end PC today can play max setting maybe in 2-4years it can only play med setting.

Understood but he likely just means improved assets for the PC version, higher quality shaders, more detailed, larger textures.

This doesn't mean they are going to be able to add assets though. They can add zones no problem (big reason why the seamless design was scrapped so that they can get this running on the PS3) but they are not going to be able to add very many more common assets (eg player weapons and armor) because they would need to be added to both version and there simply isn't enough memory on the PS3 to do so. They -might- be able to do some creative texture swapping with some LOD tricks like UE3 does but more model variation is going to be out of the question.

Now they might be budgeting memory on the current version for another expansion maybe two so they can add a handful of new item looks, but it is without question already impacting design decisions in ARR. No variation of animations across races for example and the relatively small zones are already an example.
