I'd really like to have a shot at the LS battle properly too. I was far too eager to take on MF (who I beat legitimately), so I beat LS using that tricky cheating way (strike raid through the rocks).
Mostly, I'm excited to play BBS on the console. I really hope the load times get cut a bit.
If you downloaded the content to your psp (there is an option for that on the main menu screen) you would barely have any loading screens. It was very fast.
