"Five years into the future" (Why?)

[Naraku_Diabolos]

I keep reading people's interpretation of the final cutscene being that Louisoix teleported "the adventurers" five years into the future. Now, I know that 2.0 is supposed to be five years later, but is there any actual evidence to support what thus far seems to merely be speculative fan theory that Louisoix used time magic? I've heard he's associated with "the god of time and space," but what's to simply say he didn't warp them to a safe location elsewhere -- it could even have simply been in an airship, as we saw the Imperials in one above during the finale. It could be Ishgard -- imagine if we start 2.0 there! Or any number of locations.

I guess I'm wondering why there is such a widespread assumption that the adventurers were warped through time itself to five years later. Has this been confirmed by Yoshi or anyone official, or is this all just purely speculation at this point?

You do know that there is going to be another cinematic trailer for ARR? The one that shows those same adventurers (the WAR, BLM, WHM, PLD, and BRD) riding on chocobos and with Grand Company flags? Not to mention that it contains Odin as well. There is another one planned once we get closer to the Beta/release of the game that concludes the End of an Era about those characters coming out of the past.
