No playable FFXII at E3, however apparently there was an extended trailer being shown off (I've yet to view over it as I'm at work at the moment).

If someone could verify that this is indeed an all new trailer, though, that would be great. Other than that, it looks like we'll be waiting a fair while longer for any major developments on the next highly anticapted Final Fantasy main series release.
