Beyond Good & Evil 2 has been a game that’s been in limbo for years at this point, but there are currently rumors that Nintendo might be funding the project as an NX exclusive. The story comes from Destructoid who has the source of Alexander Maier, who published the story of the recent NX rumors from Geno. In the past, Geno has been right about many rumors such as the features of Pokemon X & Y and the PS4’s capability of graphics on a DX11 level.
Apparently, the name of the game is Beyond Good & Evil: The Prejudices of Philosophers. This is a supposed reference to a chapter of the philosophical text Beyond Good and Evil by Friedrich Nietzsche.
This seems to be another situation akin to Bayonetta 2. By helping to fund the game they not only get it as an NX exclusive, but they also possibly get more people on board with the console.
In a Devs Play episode with Tim Schafer and Michel Ancel, they talk about Miyamoto when discussing Beyond Good & Evil 2 (skip to the 48 minute mark)
Will Beyond Good & Evil 2 become an NX exclusive? Only time will tell.
