Resident Evil Revelations may actually be getting a sequel. According to this leaked poster the sequel dubbed Revelations 2 will arrive on the 3DS, 3rd December of this year (which seems very unlikely honestly).
While it may not be true, there's still a high possiblity the game will get a sequel. Many fans have claim it to be the last "good" Resident Evil game in years. Even the producer, Masachika Kawata, shared interest in continuing the Revelations story line. So again, while this could very fake, I still see a sequel happening down the line.
