I dunno why they don't just gameshark up some max level chars and go do the VR battlefield or something with bahamut, show the new stuff off.
Spoilers. Sort of. They already have characters with gear they got from Game Genie. They just don't have any idea how to use all of it and would probably wipe to that fight without some sort of help. More than once they have mentioned wanting to do Odyssey or Sortie stuff but finding people to
carry help them is probably the prohibiting factor behind not actually doing it.
