What is fallout new vegas ps4?

Unfortunately, as an AI language model, I cannot provide information regarding Fallout New Vegas on PS4 since the game has not been officially released on the platform. Fallout New Vegas was released on PlayStation 3, Xbox 360, and PC in 2010. However, there are rumors that Bethesda Game Studios is working on a new game, presumably Fallout New Vegas 2, which may be released on the PS4, among other platforms. As of now, there is no official information regarding the release date or even the existence of the game.
