It's going to be released on May 25th, 2018 for the Nintendo Switch, PlayStation 4, Xbox One, and Steam for PC. Originally released on PlayStation 3 and Xbox 360 in 2011, the Switch version will bring the series to a portable console for the first time.
Why all the resolution talk? Scheduled to release on the same day, May 25, the remaster will be enhanced for PS4 Pro, and Xbox One X. The notoriously demanding game that first challenged players to explore and master its risky world in 2011 will come to a Nintendo system for the first time on May 25, 2018. In the original Dark Souls game, gamers could play online with 1 to 4 players but with the remastered version, gamers can play online with 1 to 6 other players. Moreover, the Artorias of the Abyss DLC will be included in the remaster for free.
Unfortunately, we did not get to see the actual game in action with any real-time gameplay footage during the Nintendo Direct. The game was also confirmed for PC, PS4 and Xbox One. Multiplayer will grow to include up to six players.
It is important to note that this is not an official confirmation so take it as a grain of salt until Nintendo officially announces the games for Nintendo Switch. Most recently Rockstar Games's LA Noire also made its way to the Nintendo Switch and there might be some truth to the rumor, however at this point nothing has been announced by either Rockstar or Nintendo.
I haven't looked at the reactions to the latest Nintendo Direct from fans, but I can imagine that a lot of people are dropping snarky comments about how the system gets so many older games.
The original Dark Souls turns seven this year, and we're just now starting to feel the full weight of its influence.
