I don't know... It's hard to imagine these kinds of games without Matsuno, which is probably why they commissioned him for the Tactics Ogre remake. Sakimoto and Yoshida both went freelancer. Don't know what happened to Hiroshi Minagawa, who was pretty much Matsuno's successor and already had a big impact on their titles together. I know someone with that name worked on Little King's Story but I had heard there's another dude with the same name out there... strange. I assume the rank and file developers got staffed on other SE projects over the years.

I heard a few rumors that the Quest developers didn't get along with the Square veterans. That's a shame, because I feel like after FFXII wrapped up, they should have immediately went to work on a PS3 game. Could've saved Square's reputation a bit...
