Hardware specs, 3rd party games, and even entire Directs leak all the time, so I can see why people might take those rumors as borderline confirmed. But this kind of stuff, that could only be heard by a few people high up in the company and/or their therapists, gets filed under D for Dubious in my book:
- "Phil Spencer insecure about the size of his Gamerscore."
- "Nintendo developing top secret Luigi Board to bring back Satoru Iwata as company's first spirit CEO"
- Gabe Newell selling Valve shares to Meta to support Ozempic habit.
Not that I think the Switch 2 will be a bleeding edge loss-leader (it won't). And NVidia could be pushing to showcase some of their proprietary tech in mobile hardware (though they don't exactly need Nintendo for that). I just doubt that Jensen Huang or someone close to him would publicly vent this supposed frustration, let alone that some "insider" with no rep would be the first to hear of it.
Plus, I find it hard to believe highschool-level drama like "X hurt by Y's lack of attention, starts relationship with Z to make Y jealous" actually happens in the business world. Companies backstab eachother all the time, but their motivations are money and control, not feelings.
