This is Furukawa, President of Nintendo. We will make an announcement about the successor to Nintendo Switch within this fiscal year. It will have been over nine years since we announced the existence of Nintendo Switch back in March 2015. We will be holding a Nintendo Direct this June regarding the Nintendo Switch software lineup for the latter half of 2024, but please be aware that there will be no mention of the Nintendo Switch successor during that presentation.
I wouldn’t be surprised if all the games are either to far along(/not popular enough) to bother building for the new switch. Or they will get simultaneous release on both switch and switch 2 (like breath of the wild).
