http://www.gamekyo.com/news29009_onion-knight-wearing-lunes-costume-in-dissidia-final-fantasy.htmlJust much of the same stuff. Things we learn from this however?
FF4's battlefield is the Lunar Surface. I was suspecting the lower end of the Lunar Subterranean, but the Lunar Surface works too, so long as it wasn't the Lunar Path/Upper Part of Lunar Subterranean. WE DO NOT NEED RANDOM BORING CAVE DESIGNS! So yeah, guessed wrong, but satisfied enough.
Dark Knight Cecil ALSO uses a weird spear. This also confirms that Cecil changes battle midfight, since we finally have a gameplay shot of him in his Paladin form (worth noting that portraits don't change in EX Forms as seen by Onion Knight, so obviously something else is at play! Not that "Swap at will" wasn't implying anything else.)
Cecil or Golbez's EX Burst seems to run off a Button Combo system...well, at least we narrowed down which characters would inevitably get the Blitz/Duel/Bushido style <_<
LUNETH IS IN DISSIDA!!! ...kind of. More like Onion Knight's alternate costume was based around Luneth in mind. It has white hair and a blue outfit (...though could have sworn Luneth worse Purple in his Onion Knight form), so yeah, guess this means Remakes do count to some degree <_<;
Cecil's EX Burst seems to be this move called "Holy Blade" that was in FF4 The After, which they also show him using in FF4DS' opening FMV against Golbez. Something like he jumps aireborne, spins with his sword while flashing or something...yeah, more proof Remakes are not totally ignored. Nothing is mentioned as far as his EX Mode...or Golbez's, at least as far as I can tell.
Nothing else is all that interesting beyond that. Well, at least we can distintively tell that Cecil's holding a SPEAR and not a staff. Perhaps people will stop whining about "WAAAH NO DRAGOON BARTZ BETTER BE ONE!" since any character with a lance would fullfill the dragoon quota, given the Advent Children style jumping theatrics every character seems capable of (ie everyone can pretend to be a dragoon!)
