Exactly, prime optimization for the hardware in these consoles was only really hit about 1 year ago, now they use software tricks. Depending on how much detail there is going to be in this game, I'd say medium is probably where consoles can max the game without going under the 30 FPS. One thing the PS2 had for FFXI was keyboard support, so I was able to talk to people properly, I don't know if this will be the case for these consoles, we'll just have to see.
