Why there still no PS3 version of FFXI

[Alhanelem]

That doesn't make any sense. By that logic, and u said all, they wouldn't be able to directly port HD games on the latest systems due to it's hardware.

Things like the HD edition of FFX/X2 and KH are not ports- they're being rebuilt- The PSP/GBA/ipad/whatever versions of FF1 are not ports of the original NES version- they're remakes. That is what these are- remakes.

All non PS2 versions of the game

I'm specifically talking about FFXI here. All non ps2 = PC, xbox.

PS2 classics on the PS store are, as far as I'm aware, emulated. If they did offer it, it would not be an HD remaster, it would be the PS2 version, untouched.

Either they can't or they won't,

It's most likely both "can't" and "won't". I'm sorry to rain on your parade, but a ps3 (or ps4) version of FFXI is pretty much a pipe dream.
