Nintendo planning “big Salmon Run events” for Splatoon 2, more maps will be added

This information comes from an IGN preview of Splatoon 2…

During our hands-on with Splatoon 2, we also learned that Nintendo is certainly planning big Salmon Run events, and adding more maps besides the Spawning Grounds. This was great to hear, as without additional content, once Salmon Run is “solved,” so-to-speak, it could easily suffer from a lack of a variety.

When asked if Salmon Run events would take the place of Splatfest, the Nintendo representative simply said they “weren’t discussing Splatfest at this time.”
