Where are you getting this information (rumors, leaks, quotes) that Metroid Prime 4 will not release on the Switch?

Because I have info (granted rumors) that it is almost completed.
"According to PapaGenos, as reported on the Gaming Leaks and Rumors subreddit, the development of the fourth entry in the series is basically done and has been for a good while."
The reason why it isn't released yet is because the cutscenes have been deemed to be very bad in quality.

I agree Nintendo still has a good catalog of franchises they haven't touched in a long time.

DK
Rhythm Heaven
Tomadachi
Nintendogs
Star Fox
Mario + Luigi (though the studio is defunct as of 2019)
Kid Icarus
Ice Climbers
Punch-Out
Dr. Mario

And a couple of other franchises that we can assume will come out soon
Let's Go Johto
Pokémon Legends
Pokémon Gen-remakes
Game Freak & Studio Ghibli game
New Monolith IP
Mario & Sonic at the Paris Olympic Games 2024


Games I personally would love to see make a comeback for the Switch in 2024
Rhythm Heaven: Switch
Donkey Kong Country 4
Pilot Wings: Switch
Switch Sports Resort
Flipnote Studio: Switch
Art Academy: Mario, Zelda, Pokémon
Mario, Zelda, Pokémon Picross (from Jupiter Corporation)
ARMS 2
Nintendimals? (Nintendogs Switch)
And send their Phone App Games to the Switch to buy/free downloads.
Waverace Switch (Waverace64)


Nintendo has a lot to work with and can help push Switch sales farther.
I want to say that Nintendo will do a March 2025 release for the NG, but I will stick with November 2024 until new information arrives.
But I do agree if the NG comes out in March 2025, the Switch will have a very easy time surpassing the PS2 and reaching 160+M.

"Mario, Zelda, Pokémon Picross (from Jupiter Corporation)"

I hated that they, stupidly, omitted touch control for Picross on Switch when it first released but now that they've fixed that, I'm all for Picross-everything on the system.  And you can add Waverace to that list of games; Waverace 64 was amazing when it released.  Nintendo needs another one of those.

Yeah, I think 2024 is the year for Switch 2 (still sticking with September), with Switch still having a fair chance at 10m+ for one final fiscal.

The Switch isn’t even crushing through 10mil this fiscal year. They certainly will hit maybe 14-15mil for F2023, but F2024 I see being at most 8 or 9mil.

Switch should reach 15m for fiscal ending 2024, down from the previous 17.9m.  Nintendo still has some options for Switch next year and depending on what they do, I think a drop of ~5m is possible for fiscal ending '25.  Could be more of a drop though.

With the more and more rumours we get about the Switch 2, and even those that say releasing early next year (likely not, but still can't be too far from the truth) and also with the declining sales (especially in US and Europe this year, and as we all saw Japan is starting to drop too, which all will be even more down, heck Switch won't reach even 2017 US sales .. with Europe barely matching 2017 too.) I really can't imagine how Nintendo will give 2024 full year only for the Switch. The system will finish this 2023 year with 15M at max, and next year if we say the successor is not coming, it surely won't do more than 10M. With successor will be even lower.

Me thinks the 'Switch2' will be announced as a new member of the Switch family, kinda Gameboy vs. Gameboy Color style.

I need new Rhythm Heaven before Switch ends its cycle ;(

Bro I need my Rhythm Heaven fix!

If that's the case then Switch will become a +15 year long console. Easily selling over 200M.

Yes, I agree it was rather infuriating.
And I'm glad things are better. If Nintendo was able to make some free games for the Switch (with in-game purchases), and had daily-tasks or something (like Duolingo's day streak counter) then I think they would be a great source of quick entertainment. And would expand to a wider audience that could be interested in playing their more expensive $60-70 games.

Waverace was a blast, thank you for reminding me, Ill add it to the list of comebacks, they sit on so many hidden treasures it actually astounding that they don't just go crazy with IP's.

September as a release month does make sense, for it gives Nintendo time to figure things out, and also get real life advertising, the word of mouth and such hyped up for the holiday season.
