Final Fantasy is known for being experimental and trying different things, Sakaguchi has even said he enjoys that aspect of the series. And you haven't even played the game yet (yay, a demo), and you want to disown the game for a minor thing like that? *adds in LunarWeaver's post*

Anyway, if you want ATB, play FFXIII when it comes out. Or, goodness, play the older FFs again.
