USK, Germany's ESRB equivalent, has rated Resident Evil Code: Veronica for PS4, indicating that the game is coming to modern consoles as either a port or remaster. However, the USK has since removed its listing for Resident Evil Code: Veronica, which likely means that it was posted in error.
Before the USK could remove Resident Evil Code: Veronica's PS4 rating, NeoGAF user YianGaruga managed to record the details. The game was given a 16 rating (in ESRB terms, "M" for Mature) and the listing was originally posted on March 17th. Since the now-removed listing was posted not too long ago, it could be an indication that Capcom is preparing to announce the PS4 version of Resident Evil Code: Veronica soon.
As stated previously, Resident Evil Code: Veronica on PS4 would likely be a port of the HD version of the game or a complete remaster like the Resident Evil remake and Resident Zero remasters that Capcom released over the last couple of years. Alternatively, it's possible that Resident Evil Code: Veronica is the next PS2-on-PS4 game, since the listing names the PlayStation 4 as its only platform.
While there are numerous possibilities when it comes to bringing Resident Evil Code: Veronica to PS4, the most likely scenario is that the game is a port of the HD remaster that released five years ago. It's also probable that the game is coming to PC and Xbox One as well, considering the fact that almost every other main series Resident Evil game is available on those systems in addition to PS4.
If Resident Evil Code: Veronica is coming to modern consoles as the USK listing suggests, there would only be two main series Resident Evil games missing from the PS4 library. Those games are Resident Evil 2, which is getting a remake, and Resident Evil 3: Nemesis, which would likely need an upgrade in the vein of Resident Evil HD Remaster before it made its way to modern consoles.
Perhaps if the Resident Evil 2 remake is profitable enough, Capcom may take the initiative to give Resident Evil 3 the same treatment, which would give fans the chance to play every main series Resident Evil game on one system. Of course, that's assuming this Resident Evil Code: Veronica listing is real, so fans will need to sit tight for an official announcement from Capcom before getting too excited.
Resident Evil Code: Veronica is available now GameCube, PS2, PS3, Sega Dreamcast, and Xbox 360.
