I know, I know. The first thing you're going to say, "NOPE THIS IS A RUMOR! THIS SHIT'S FAKE UNTIL IT INEVITABLY DOESN'T OCCUR AND IS THEN PROVEN "FAKER-THAN-FUCK!" But still this seems very plausible. Even if the "World of Versus" part is ultimately fake, it also covers some information about the confirmed DLC planned for the Season Pass throughout the rest of 2017, which you may or may not be fully versed on as of yet. If you're into FFXV, I suggest giving this a view.
I hope this rumor is true, though, especially since it could mean the inclusion, as long last, of the shocking amount of "cut content" glaringly absent from the final build of FFXV. There is plenty of missing footage to be found within the trailers once the project was renamed to "Final Fantasy XV," but there is another truckload of it if you consider all of the scrapped ideas from project "Final Fantasy Versus XIII."
I really hope that this "World of Versus" rumor is real, and that it will contain a lot of the content planned from Versus XIII--especially the chaotic events at the palace in Insomnia and the conversation (and other potential interactions) with Lunafreya.
