So one of the big limitations of the PS3 is it's hard drive space, which can be fixed by buying bigger hard drives but must always account for the lowest (even though its 20, realistically it's going to be 80 for 99%) and vram.
This means that the more crap they add, Jumping for example, more menus, more items, more graphics, will use up more vram and eventually lag the game out. Especially in crowded areas.
This is no doubt why the PS3 version has been delayed, they even confirmed this.
The options then either become hard drive swapping, which can be rather slow (that's kind of why you have a Page file in windows), the other is to use flash memory.
In Windows Vista / 7 they have a thing called Readyboost, where your flash drive can sort of act as additional ram as necessary. While on a fast PC you won't notice it, but on slower barely bootable PCs it's major difference.
So, what I'm saying is, in theory couldn't they ship FFXIV for PS3 with a 4 gig flash stick formatted in FAT (the OS the PS3 recognizes) that can be used as a data swap/additional storage? Flash memory is insanely cheap, and adding a 4 gig stick would basically add $1 to the cost of the game, and would probably triple the performance of the game if it was mandatory.
I'm just saying, it works for Windows, and we already know the PS3 is going to be what limits FFXIV, the same way PS2 limits FFXI.
Oh, and of course code FFXIV to make use of it.
