It's coming, they mentioned it on their Quakecon panel just a few days ago, it's just taking longer than expected because of working from home.

So what’s the reason then?

With COD, Activision doesn’t manage the same volume of sales as the ones you mentioned. 

Every COD game on PS4 crossed the 5 million mark easily in a couple of months and I reckon that most COD’s on PS4 already crossed the 10 million mark.

Why they would spent money to port COD to switch only to sell 1-2 million units LTD when they can sell that quantity on PS4/Xbone/PC in a couple of weeks??

Activision should at least test the water and put the mobile version on the Switch.

I do think CoD is coming eventually, but not until 2022-2023. PS5 and Series X sales are going to be slow out of the gate. CoD will have to come to Switch if Activision actually wants to make some money on them.

Probably because they can't push all those microtransactions, lootboxes and whatsnot nearly as successfully on the Switch than on it's competitors. So sales on the Switch would result in less revenue than on competing platforms, which for them is generally considered a net loss.

Either that, or Bobby Kotick hates Nintendo or the Switch with a passion and rather makes less money than porting their flagship game.

However, I really don't mind it's absence. I am hoping that CoD and Activision die a painful death since the day they bought Blizzard, so...

The witcher 3 is old now though doesnt really push the newer ps4 pros or anything

A 360 version port of a last gen game would be a better option, and much better recieved if they want to just test the waters.

I hope so. I would be happy with CoD4 MW remastered. Good multiplayer fun!!

Witcher 3 is nowhere near one of the most demanding games.

The game was 900p on X1 and 1080p on PS4. The dynamic resolution of the Xbox One X version displays between 1800p and native 4k.
Also the game came out less than two years after PS4 and X1 launch. The game would look and run vastly superior if developed today.

With that being said, I don't see why MW wouldn't run on Switch. 720p 30 FPS should be possible. Biggest issue would be HDD space though. 100GB at the very very least.

Probably not on Switch. But Switch 2 will probably have COD. Activision and EA haven't supported the Switch much, and that's not entirely bad. But since some people do wanna play their games on Switch, they should be there.
