Platinum Games have launched an official Twitter account and the first post just happened to be related to Bayonetta.
The images contained pieces of artwork for Bayonetta 1 and 2 with one image in blue while the other was in red. This has led some to believe that the games are being ported over to the Nintendo Switch.
Please keep in mind that Platinum Games nor Nintendo have confirmed that this is the case. Expect some sort of announcement soon.
