Soundwave on 24 December 2023
Hard to guess when you don't really have any idea what the software pipeline is like, but I'll guess an announcement in March with a launch in September if the software and manufacturing is ready.
If it's a November kind of launch, well then maybe they just hold off until April or later.
I think in Nintendo's view they only really had 4 and a half months to really market the Switch, and the same amount should be adequete for Switch 2.
