BTW, something that was not mentioned:
-Ifirit and Shiva (or at least in her case heavily redesigned) seem to have been replaced by Doomtrain and two new summons.
Damn this game oozing a shitload of charm. :D
EDIT: Forgot to say this, but the video may take a little while to load.
EDIT2: Seems like the video was taken down. =/
EDIT3: Seems to be working again, weird.
A Niconico Broadcast just finished awhile and here is a summary of the most important things.
-Some bosses have huge amounts of HP
I see that Squeenix still can't be bothered to figure out how difficulty works in an RPG.
It's pretty normal in an RPG that a few bosses will have high HP, doesn't mean they are just a sandbag of numbers or that it says much about the general balance of the game. From all the demos, impressions I've seen and read most Bosses in this game regardless of HP are pretty challenging thanks to how the battle system works.
Plus the Producer of this game was one behind FFIV DS most challenging but fair fights so, I'm not worried about difficulty here.
