We already know the answer to that one Plant (PS 4, XB One, and PC first; any other platform maybe later...if it's profitable to do so).
If we get lucky, it will be the same as past Nintendo CoDs -- there will be no announcement until the eleventh hour, it will launch with just four months of support, and we get no DLC outside maybe the usual preorder multiplayer map.
Also Activision would strip out the gore if there is a Switch version.
I actually would NOT expect that last bit. Switch's adoption population seems to be more adult this time. Maybe the just at launch, but still. Anyway, I'd expect a flat-out omission of a Switch version before a censored release. When's the last time a Nintendo version of a AAA game for censored?
