A major player in the fighting arena might be coming to Switch, if a banner reportedly hanging in Seattle is any indication.
A picture has been posted on Reddit sourced to a deleted post on the former Twitter showing what appears to be a banner hanging in the Seattle Convention Center. The banner, located outside the Atrium Lobby, is advertising a Switch port of 2021's Guilty Gear -Strive- with an invitation to preorder.
Arc System Works has ported some of their previous fighting games to Switch in the past, including Dragon Ball FighterZ and DNF Duel.
