The bombshell news out of Nier's tenth anniversary celebration is the remaster/reworking of Nier Replicant on PC, PS4, and Xbox One. But, that's not the only thing Platinum and Square Enix have up their sleeves.
There's also an upcoming Nier game for mobile devices. Called Nier Reincarnation, it's a role-playing game that's being developed by Applibot. Reincarnation is coming to both iOS and Android, and an automated translation of the game's website makes it seem as though it'll be free-to-play with microtransactions.
Other than that, we just have the teaser trailer that's embedded above and the piece of key art that's in the gallery below.
