The Korean Ratings Board has rated Resident Evil 6 on their site, and so it seems to be coming to PS4 and Xbox One, this according to Gematsu. The game was launched originally on PS3 and Xbox 360, and arrived on PC one year later. Capcom has not officially confirmed anything about this remaster, so for now it's still a rumour.
Even though it's a rumour for now, the Korean Ratings Board also leaked the remaster of original Resident Evil before its official announcement, so maybe this one will turn out to be true as well? Time will tell.
