The main area I'd like to see discussed next, more so than anything actually, is the levelling system. I've mentioned this somewhere in another thread, but it will be interesting to see where Tabata takes it. Will there be traditional levels as seen in the earlier FF's and, if so, how will characters learn abilities? I would love a return to something similar to FFIX, where you level up in the normal manner but learn new abilities from weapons and armour.

I'm thinking though that it will be a more streamlined progression like X and XIII, where levels are removed and replaced by the Sphere Grid and Crystarium. The "hold x to level" was pretty boring in XIII. But then so is having to move / unlock / learn / move / unlock / learn.

There's definitely room for innovation.
