Well I know they said that about 3.1, but I'll be surprised if 3.2 doesn't include the fight against Sephirot(h) as an MSQ fight. Use like parallel branching paths or something, so it eventually becomes necessary for the MSQ but hardcore players can do it as soon as they like.
... 3.1, expected that. Thordan was already groundworked, just took some tweaking. I'm quite salty over 3.1x in general, though; Void Ark is nice, but the MSQ was short, had no big fights, and the Anima weapon is so grindy that I don't feel like actively trying to get it. But I digress.
