Nintendo said they will announce/reveal something this fiscal year, that's it. No word about launch.
The rest are just rumours and just a bunch of dudebro's who replaced 2023 with 2024, and now have to scribble in 2025 pretending they never said they were 99% sure it was releasing earlier.
Tbh, as importent as they were to the nacent development of the games industry, based on past and recent behavior towards fan games, I kind of hope they eat their hats on this.
If it's still 9 months away, there's no real reason to announce it publicly before the Christmas season. The fact that the original Switch's sales are flagging is not a reason to announce, since it's not launching in time for the holidays. Its announcement isn't going to spurr Switch 1 sales.
When it's announces will be entirely deoendent on when retailers need to know launch details. Once it's outside of Nintendo, they'll have to announce things publicly or risk losing control over the narrative.
They're waiting that the tech is becoming the past gen. They can't launch something from the current gen, it must be 3-4 gens behind and compensate that with their coding geniuses that can still make masterpieces with the limited resources available. Maybe it's going to be something as powerful as an iPhone 11 would be mind-blowing 🤯
