If I have to wait, I'll wait. I'll be able to see if the changes will be a good thing or a bad thing (I rather enjoyed FF12, 'cause it was still, you know, the same sort of Final Fantasy deal, except in real real-time and with people moving around a little bit more, I mean, you introduce an "active" ATB and introduce actual movement into it and then suddenly everyone starts bitching about it. It's NOT THAT DIFFERENT."
Edit: Combat in FF13 doesn't look too different either, just maybe a little more cinematic, like what PoP tried to do. Difference is, Final Fantasy is more Turn-Based to begin with so you're not going to have much complaints about that.
