New Warzone Leak Hints at Potential Vanguard Map Release Date

It is inevitable that the new Call of Duty: Vanguard to release in 2021 will have a Warzone tie-in, allowing for cross-promotion between the popular battle royale title, and a new COD title.
Famous Call of Duty leaker on Twitter @ZestyCODLeaks back in April regarding "x2" files data mined for an unknown event at the time. ZestyCODLeaks and those reading the leak figured it would be something big, seeing as when Black Ops Cold War was revealed, the data mined files read "x1."
?MAJOR EVENT COMING SOON?

I've actually known about this for a while now, but I felt like I didn't have enough for a post.
There is a NEW major event coming called 'X2' that will feature the 'Armoured Train' and 'Ambushes'.
BOCW's Reveal Event was 'x1_fin' ??

Any type of news relating to Call of Duty: Vanguard has still been pretty scant, as there was no word on Sledgehammer's new title at the most recent E3.
Despite the lack of substantial and confirmed news on the game, fans remain hopeful through the avenue of Vanguard leaks that many got their hands on back in early June.
As November comes closer, more concrete content about Vanguard will come about.
