By the time this thing goes through and they start working on games for Nintendo's system it won't make sense to work on a Switch game as Switch 2 will be coming out probably mid-to-late 2024. First CoD on Nintendo will hit in 2024 or 2025.
Possible in 2024 they just do a port of an old CoD just to put something out quickly. But after that it should be the new games, no reason for it not to be. Switch 2 obviously won't be as powerful as current gen consoles, but it should be about as powerful as X1/PS4. Considering Microsoft would be making these to run on Xbox Series S they should run on Switch 2 with just a bit of adjustment work. Drop a few graphical details and drop resolution (then bring it back up some on the cheap with DLSS) and Switch 2 should be able to handle it fine.
