Seriously though why the Alternate Realities
Omen can be called a dream, and there doesn't need to be an AU after the time skip that can just be the afterlife. I mean Alternate Realities opens the can of worms that allows for Versus XIII to happen whether it be called World of Versus or Versus XV. It allows for it to happen.
Especially after these World of Versus DLC rumors popping up, which could explain why on earth there is an AR after the timeskip, but if they are trying to please those that want/wanted Versus XIII, well they've lost the plot entirely, because unless the length of that DLC(Which I would assume they would try to make Versus XIII, I mean I hope they don't because that would be a waste of both Versus XIII, and DLC would be better to be Dark World. Now if it's more than just a DLC, and something like this. Then you got something special, that if is great people might actually buy, just market it right. Hell if marketed well, and it ends up being a great game/game series, then the entirety could end up outselling FFXIII's Trilogy, which I hope the 7 Remake does, like by a lot, because Jenova's eye nipples are more likable than the cast of FFXIII.
World of Versus is in fact what they are calling the relaunch of the Final Fantasy Versus project itself, and no, it is not an expansion to FFXV. The way it is being done will make perfect sense. Square realizes the demand internally and externally is beyond warranted.
Rumors are fun to discuss

However if World of Versus assuming it's true if it's a DLC, and tries to be Versus XIII in it's entirety, it's DOA, you'll just end up pissing off those that wanted Versus XIII, and those that wanted it would be indifferent either way, better idea to just call it the World of Dreams at that point, or Noct's Nightmare. Cuz World of Versus especially with that word in the title, yeah, and hell Tabata being attached to it as well, as director? Those that really want Versus XIII see the man as tainted as Ardyn after absorbing the Starscourge. Him+World of Versus just being a DLC = Absolute disaster.
If this World of Versus thing ends up being true, it has to be the current rumor, not the rumor of several days past, because if it is that one and not this one. Unless Tetsuya Nomura's name is attached as director cuz there is no way these people will trust Tabata like at all, and the expansion is over 60 hours long and close to 100 in pure story content, and contains everything from the Versus XIII 2011 Trailer, Noct and Stella's conversation, the 2013 Trailer Leviathan fight or close to it. Yeah at that point it's better to just make a series of games, because that DLC would be over 60 dollars, and ain't no one touching that. Cuz if it's 20 dollars, has about 15 hours of content, and they call it World of Versus, and Nomura isn't attached to it in anyway shape or form , it's DOA. Like Rest in Piece DOA. However if it's the current rumor, with let's say an DLC for FFXV that acts like a Prologue to it, then you know what, the DLC might sell enough to fund the game itself.
