I think it is pretty obvious Year Zero will definitely drop in 2022.
One thing, it's the 15th anniversary of its 2007 release.
Another thing, the dystopian future the album tries to warn us about just so happens to be...
::drum roll::
2022.
You heard it hear first.
It'd be cool if we get a new NIN album/sequel as well to tie into it all. Perhaps it could expand upon the Trilogy and its ties to Year Zero. Perhaps we'll finally get Bleed Through, as in elements from the alternate reality of Year Zero's 2022 bleeding into our reality 2022. Maybe we haven't completely avoided that future. We're just on a different path towards it.
Oh, wait sorry... I think my shrooms kicked in when I wrote all of that.
