This is according to a job listing on Riot’s website in which it seems to reference the Nintendo Switch. While there is no specific reference to Wild Rift on the Switch, it does seem to call for developers who are familiar with shipping cross platform games, covering the Xbox, PlayStation, and the Switch.
There is also a position for a software architect where according to the job requirement’s description, “Experience and understanding with two or more of the following platforms: Microsoft Windows OS (desktop), iOS or Android OS (mobile), XB1, PS4, Nintendo Switch (console).”
We wouldn’t be surprised if Wild Rift were to come to the Switch. Nintendo’s latest console seems to be pretty popular with developers, more so than its predecessor, the Wii U. Plus, with the portability of the Switch and Switch Lite, League of Legends: Wild Rift does seem to be a perfect fit. Details are scarce for now, but the company is planning for a 2020 release, so we expect that more details will be shared soon.
