The article that calls Splatoon Raiders a Switch 2 exclusive in the Splatoon series timeline is Splatoon.
English Wikipedia’s Splatoon article contains the franchise overview and a chronological list of its games. In the spin-off section, it describes Splatoon Raiders as an exclusive for Nintendo Switch 2 and places it after the mainline entries and expansion content. The wording is therefore found in the series article, not in an article about another Nintendo franchise.
That context matters because Raiders is the first spin-off in the Splatoon series and the fourth installment overall. The article identifies its planned release as July 23, 2026, following Splatoon 3 and its Side Order expansion. It also notes that the game follows Deep Cut and an unnamed mechanic in the Spirhalite Islands.
The distractors are unrelated article identities. Super Smash Bros., Animal Crossing, and Mario Kart each have their own franchise histories, but none is the article used for this Splatoon timeline entry. The answer refers to the Wikipedia article title, not to a character, developer, or platform.
