Patch 3.2 Trailer is Up

[Nalien]

I'm curious, has the Dev team discussed how they're structured?

There have been some off hand comments over the years, but I'm far too lazy to go digging for them. From what I've gathered, we've got;

PvE team, which itself has some sub-teams (we've got specific references, like the people making Sephirot are the same who worked on Thordan and Titan).
PvP team, I believe this was mentioned around 2.1 when we were first getting PvP. Yoshida mentioned they had a whole separate team working on PvP.
Housing/Gold Saucer. This is more of an assumption, but there was a comment that Housing content was delayed because "the team was busy working on Gold Saucer" around 2.5.

I think we also have a team that makes Minions. Don't think that is their only role, but I recall a comment from Yoshida about how they just keep churning them out faster than they can find a way to put them in the game.

As far as PvP goes, I recall the comment being specifically aimed at concerns that SE can't do PvP. Yoshida assured players they had a whole team dedicated to making the content and working on balancing (where as FFXI was guilty of no such thing, they just allowed PvP with no attempt at balance, heck PvE in XI was horribly balanced). Still, given we got Wolves' Den, Secure, Slaughter and Seize with no cost to dungeons, one can assume the Feast would be no different. I believe Yoshida specifically said we'd only be getting two dungeons from now on so they can try new things. Feast is not a new thing, it is a continuation of what we've been getting since 2.1, something that was promised at 2.1 in fact (as far as Seasons/Leaderboards go). Diadem, Stone, Sky, Sea, Hall of the Novice, and Mentors are new things.
