Something odd seems to be happening with the Bayonetta Steam page, as a few people have pointed out a weird post thrown into the news section. Earlier today, the image below with the headline "Baa" was loaded to their page, and as funny as it is to see the team mess around with people, everyone is trying to figure out what it could possibly mean.
The popular thought going around is that this could be a tease Catherine, an Atlus IP that's more of a visual novel/puzzle game, but that's speculation at best. If SEGA holds down their usual pattern for big reveals, we should expect to see something about what this means within the next month. Unless they're playing the long-con, then we'll see what E3 has to offer.
