Some reports from Digital Foundry:

• A "Switch Pro" was once considered, but was then cancelled

• Efforts have shifted to a proper successor to the Switch

• This successor is unlikely to be released in 2023 according to them

My first guess was the next gen console would launch with the new Zelda in May. Worst case, it should launch later that year.

Creatures, Inc., one of the companies behind Pokémon, has a job listing for "R&D for next generation hardware".
