As The White Wizard of Fynn pointed out, the current gameplay video shows you switching to other party members to pull off special moves and finishers so there is no reason to believe this is the case at the moment.
I disagree, the combat I've seen is very reminiscent of KH's battle system, the FFXII comment only pertains to the interface of the game where the Gambit system allowed the player to not have to fuss with too many menus by setting up the A.I. to do it for you which frankly isn't that different from most Action-RPGs. Basically, he's explaining that you won't be raped by goblins while trying to scroll down a menu looking for that cure spell because you'll already have it set up by buttons and A.I. prompts. You know unlock KH1 where the menu system made doing anything that wasn't button mashing a chore and an easy way to let enemies and bosses get a free hit on you.Plus on top of that, the battle system, is not KH style anymore.
It's like playing ff12 without being able to switch characters.
Honestly I never bothered with the hotkey nonsense in ME and I've always felt the Gambit System was well designed and could easily be expanded in future installments, of anything it spoiled me on tolerating other games with A.I. partners because it offered far greater control, so personally its a welcome return if the designers feel we have to deal with A.I. partners, I'd rather have some real control over it after dealing with the nonsense from XIII.
Versus XIII was always touted as a very different FF experience, hell Nomura even said it wasn't a numbered title because it was going to be radically different game from traditional FFs so when SE decided to bite the bullet and make it FFXV, I didn't expect that to change and I'm just finding it surprising to see so many people feel it was suppose to.. Frankly, I feel that everything I've seen and heard about the game is a vast improvement over what we were handed last gen.
