The Nintendo Switch version will be ported by a development studio who is familiar with the Call of Duty franchise. The Switch version of the game will support the game’s DLC like its counterparts and will feature the system’s unique HD Rumble and motion control options.
Industry insider Marcus Sellars backs this up, massive success revealed at their most recent quarterly briefing, it would make sense that Activision would want to take advantage of that fact and release the game on the Nintendo Switch. They did come out with Call of Duty Ghosts and Black Ops 2 for the Wii U, so this is not unfeasable. There have also been rumblings from analysts that the next Call of Duty would be Black Ops 4, capitalizing on Call of Duty’s most successful brand.
Hopefully, Black Ops 4 is just as good as Call of Duty: WWII. The franchise desperately needs to sustain the momentum that WWII has generated.
