I'm pretty much in full agreement with all the reasonable people here. FF brand fatigue is setting in; not terminal yet, but Square needs to start thinking about changing their strategy now; FF4 is going to be less affected than a spinoff-y game but it's also a good barometer to watch.
I'm not sure Square can even get back to the point they were at during the sfam/psx years. That many new IPs and experimental titles requires a bench strength that they just don't have. Can anyone in this thread even name a current S-E game director that isn't Kitase, Kawazu, Nomura, or Toriyama? They'd have to make a concerted effort to create agile development teams with young people -- unproven directors with new ideas -- in charge of them, something I really don't see happening in the near (or even far) future.
