French site Game Blog spoke with Dragon Ball FighterZ producer Tomoko Hiroki. Despite what some may say, the game not being on Switch isn't a matter of the system's technical specs or lack of power. Hiroki added that there hasn't been any trouble porting over Dragon Ball Xenoverse 2.
It isn't clear why Bandai Namco and developer Arc System Works skipped on Switch for Dragon Ball FighterZ. However, Hiroki did say that if fans show their interest, they could bring it over. Hiroki did caution that Dragon Ball FighterZ may not come to Switch the same time as other versions, but they're open to considering it.

Time to tag Arcsys and Bandai Namco and show them there's some fan demand!
edit: also reminder that GGXrd runs on PS3 if some still have doubt it could run on Switch...
