In the "Levy's letter future" the entire rescure team (Natsu, Mira, Wendy, Happy, Charle) and Yukino died in the initial Dragon attack, meaning they would already be dead by now! So unless they fiddle with timetravel and inadvertedly restore the "original" timeline, that future very clearly will never happen, which completely voids any content of this letter.

So please stop using that already voided letter as proof or a hint about what will happen next.
