The last game in the Pikmin series was Pikmin 3, which arrived in 2013 for the Wii U, however, we may well know the name of a future instalment, as a game called Pikmin World surfaced with a Dutch retailer just recently.
The site says the game is due for the Switch, although Nintendo hasn't confirmed anything just yet, so take this with an extremely big pinch of salt, especially the expected arrival date of March 24 (less than a month away).
Are we overdue another Pikmin game?
