I remember the interviews with Nomura saying that very little had been done with Versus when the initial trailer was released. But I also remember early interviews that described the Fabula Nova Crystallis series as the main focus of their efforts this gen, with XIII, Versus XIII and Agito being the initial games in the series. Of course we all know that issues with XIII and the White Engine threw a wrench in all of that,
Well, to be fair, didn't they also announce FFX, XI & XII at the same time as well, with X-2 being announced after XII but released before it? And it took them almost 6 years to fulfill those promises. This is only OMG UNACCEPTABLE if you view it in a way that they should release mainline iterations XIII, XIV and XV during one generation instead of doing these different XIII games, when in reality Versus & Type-0 are every bit as big & important projects to Square Enix as a mainline XV would be. They are just a bit TOO different from mainline releases to get that next roman numeral.
but that really only points to the potential management issues over at Square Enix that people have been speculating about all gen.
Square Enix has admitted that the way they worked on games is too dated for games of current caliber. They started having some problems in the PS2 era (best examples being the problematic development of FFXII as well as some games not living up to their potential/name, i.e. Seiken Densetsu 4), but it all culminated in the White Engine/Crystal Tools fiasco. They've acknowledged this and have been working to fix all of this (take the Luminous Engine, which they've been preparing with next-gen in mind so that they can jump to PS4/Xbox 720/Wii U development a lot more smoothly). Change simply doesn't happen overnight. But really, just think of Square Enix post-2008/2009 and see how they've been a lot more efficient while also delivering some great quality games (the likes of Birth By Sleep, The World Ends With You, Type-0 and even XIII-2 seems to take plenty of steps forward from XIII, at least gameplay-wise)
Versus is a long time coming, and its hard to see it having the same impact that it would have had it come out a year ago.
FFXII came really late in the game yet that didn't stop it from having an impact and getting tons of praise from critics & fans alike (though, with the usual "we are against this change" fans on the opposite end hating it)
