A single page scan http://media.psu.com/media/ffxiii_battle_scan.jpg
of new ingame Final Fantasy XIII battle system

as expected, this means Famitsu will have ingame battle stuff next week also =D (plus there's Jump Festa event this weekend)

Also, pigtails girl name is revealed as ' Wolva-Daia Vanilla'

Other translation of commands (shown in battle menu)

Fight
Launch (aerial attack?)
Fire
Firaga
Cure

As shown in the very first trailer, it appears as though the battle system has stayed largely similar to the original concept, you stock commands together from the menu, and string them into one long chain of attacks, then execute them as like a combo (and looks very flashy)
