A disney RPG from Square will be made to fit the demographic they are trying to attract, and that is to influence young audience and create a new batch of future RPG players.
It will probably turn out to be a good thing for Squares bottom line but all it does IMO is postpose that new hardcore RPG Square has on the drawing board (or at least I hope they are dreaming up a new world and new experience, on top of a Vagrant Story and Front Mission Sequels)
I just can not get excited about anything Disney in a videogame
