The Activison-Blizzard acquisition is still undetermined as Microsoft battles both the Federal Trade Commission in the United States and the Competition and Markets Authority in the United Kingdom. The head of Xbox, Phil Spencer was asked during the recent court battle with the FTC whether Call of Duty on Nintendo Switch would look the same as it would on Xbox Series X consoles. Naturally it won’t, so Spencer answered the question by saying “I think it will play as a great Switch game. I don’t think it will look the same.” He then said that they would aim to make sure that the performance of Call of Duty on Nintendo Switch would be equal to, or better than, other third party Nintendo Switch games.
Phil Spencer: We would aim to make COD on Switch of equal or better performance than other Switch games

I thought the COD in WiiU did amazing. It was beautiful, played well and exposed Nintendo gamers to a whole new(lack of a better term) battlefield
I totally agree, the Wii U version of COD was great. Even the Wii versions of it was good.
The Wii U versions of COD were great. It allowed Wii remote control as an option, which is superior to the Joy-Cons. Another brilliant feature and I don’t know why other developers didn’t use it was that it allowed one player to play on a TV with Pro Controller or Wii remote and nunchuk, and a second player to play with the gamepad with their own separate screen. Sonic & All-Stars Racing Transformed was another game to have this feature.
The Wii U was closer to the competition in terms of performance. The Switch isn’t, and it’s probably the largest the gap has ever been for a Nintendo platform.
Call of Duty: Scarlet and Violet
If Call of Duty can run on the Wii and WiiU, Then C.O.D. can run perfectly fine on The Nintendo Switch. Stop being silly. Sure it won’t look as pretty, like on the Xbox Series X, but it will still play fine.
I’m guessing none of you played Doom Eternal on Nintendo Switch?!! It plays perfectly fine!
Black Ops II was released in 2012, which also released on the ps3 and Xbox 360. I believe the WiiU might would’ve handled Black Ops III which released in 2015, but the game is 150gb. It’s gonna be interesting to see what a recent or new cod game on the switch would look
