In that link is a clear example of what can be done, with a update this elements.
Weather effects
Water Effects
Shaders
Shadows
Lights
Background detail.
All this elements can be introduced, by "Updates". Not is necesary kill the ps2 users, just work on pc/xbox360 users with this graphics update.
I play aion 2.5 and i can say guys there after since this was introduced. The diference is a lot.
Now the main reason for the devs say "Ps2 limitation is this". In japan
almost all players "Hate play on pc and xbox360". In japan they love play on jp consoles. Actually the 80% by japan players play ffxi on ps3/ps2. Yes they hate play in PC and xbox360.
The devs can give us our graphic update for pc and xbox360, and keep give service to the jp guys.Kill the 70% from the ffxi population not is cool. (We have to be realistic, the JP comunity is x 2 or almost x 3 more big than America/Europe.)
Now after the graphic update, they can release the new ffxi ver on ps3 so the jp guys will be happy.
