First, I would just like to point out that FFXIV is being made on the same engine as FFXIII has been. The amount of detail they have been able to put into FFXIII is nothing short of stunning (the ease of the game on the PS3 is also stunning, as my fan on the PS3 has to speed up less often for FFXIII then it does for most of my other games)
That said, it is likely that the game will first be designed with the PS3 in mind, and everything they include into the game, will be capable of being displayed on both PS3, and PC equally (same idea as how they build FFXI to display equally to PC and PS2). Now this is not to say the resolution will be the same, as there will definitely be PC's around right from the get go that are able to play the game at a much better resolution (once again, same as how FFXI was designed).
I honestly don't believe we will be hearing the phrase "due to PS3 limitations" for at least 2 years into the game.
