Wonder if they'll make the combat more like an action RPG, something like Crisis Core or FFXV. I hope the materia system is kept. Either way I'm cool with it, I either get to go through and experience the world and characters with a new battle system or I play a classic again with an already solid battle system but with updated HD graphics, soundtrack etc. It's things like story and voice acting which could let it down, personally speaking.
Well we know one thing about it already, Nomura's confirmed that cross dressing Cloud will be included (why do so many people ask about this?!)
