Well, contrary to the Bioshock remasters, Dark Souls Remastered will be a separate product.
There has been no official confirmation of this from Dark Souls publisher Bandai Namco.
However, the Twitter user notes that even if the game is being remastered for PS4, don't expect details to be revealed soon. It included information regarding a remaster of the original Dark Souls coming to the Switch in the future.
The game comes with the Artorias of the Abyss DLC, but no new content has been announced. The series came to an end a year ago. The box set will include all three Dark Souls games, each respective game's soundtrack, framed art, Dark Souls' themed bookends, and three dictionaries containing the entirety of Dark Souls' item list.
Dark Souls was initially released in 2011 on PlayStation 3 and Xbox 360. The inclusion of the Dark Souls franchise in the ever-growing catalogue of Switch games goes right along with Nintendo's decision to include more mature titles like Doom and The Elder Scrolls V: Skyrim. While the Switch version could conceivably address that level of difficulty by toning it down, somehow we suspect that Dark Souls Remastered will be just as hard to master as the original. While PC, PS4 Pro, and Xbox One X players will be able to enjoy 4K, the Switch will run at 1080p and 30fps in docked mode, and likely a lower resolution when in portable mode.
