And yet JRPGs like Lost Odyssey, Ni No Kuni, White Knight Chronicles, Valkyria Chronicles, etc were possible on current-gen hardware, and JRPGs like Xenoblade Chronicles, Pandora Tower and The Last Story were possible on the fucking Wii.
Hey, Nomura, you know what Xenoblade had? An open-world. You know what the Last Story had? Towns. You know what Final Fantasy games on much more powerful hardware lacked this generation? Both. Don't give me this 'only possible on next-gen' bullshit when recent Final Fantasy games have yet to match the standard set on games running on previous generation hardware.
The problem, I suspect, is that Squenix simply announced the game too damn early, before they'd ever got any proper work done on it. It's a habit they've had for a while: announce a game as soon as it gets greenlit. I very much doubt VXIII/XV has been in serious development for more than a couple of years, if that. I imagine the real reason for the delay after announcement was the majority of the internal team getting moved to try and help out on the clusterfuck that was Final Fantasy XIV. They've had to rebuild the entire game from scratch, and I'm sure they had to reasssign teams in order to do so.
