Definitely something to treat as a rumor for now, Russian retailer Videoigr briefly listed both Resident Evil: Revelations 2 and DmC Devil May Cry Ultimate on their website, before taking them down shortly after.
When they were up, Resident Evil: Revelations 2, a supposed sequel to Resident Evil: Revelations, was shown as coming to the PlayStation 4, PlayStation 3, Xbox One, and Xbox 360. As for DmC: Devil May Cry Ultimate, that was listed for PS4 and Xbox One, meaning this would likely be a remaster of the PS3/360 game, probably including all of the DLC.
So, while these two listings could prove to be false, it’s important to note that gamescom is happening in just one month, and Videoigr did correctly leak Assassin’s Creed IV: Black Flag ahead of time.
If Capcom does announce Resident Evil: Revelations 2 or DmC: Devil May Cry Ultimate at any point, we’ll let you know.
