If you walk the daisy chain of "sloppy reporting based on another sloppy outlet's reporting" it all comes back to a chip leaker who
this thread actively performed a debunking operation on, by sending them a false leak and watching them post it immediately. OreXda, the "leaker" in question seems to publish literally anything sent to them, with no verification, and regardless of source.
But even worse, OreXda didn't make the claim that it was due to 5nm capacity issues. That was added by another reporter, simply speculating, which got picked up by other outlets as the rationale. The whole reporting chain comes down to this
contextless tweet from a known unreliable source.
You're talking about hardware related leaks, and hacks. We're referring to devkit related leaks. The difference matters.
Suppose I am known for making cakes. And right before I announce my Surprise Cake, it's pretty common for folks to say "hey, OldPuck is making a cake." So when Cake Rumors start, you know Cake is probably incoming.
Now suppose someone breaks into my house and sees butter, eggs, flour, sugar, chocolate on my shopping list. "Oh shit, cake is coming! And it's chocolate this time!"
And of course cake is coming, but not any time soon. The Cake Rumors in the past were based on people who live beside me smelling my cake. Just because you know the flavor this time doesn't change the fact that the information comes from a different source (someone breaking into my house), and so you can't extrapolate timing from this new rumor.
If devkit related info is leaking, that means 1) that 3rd parties have devkits and 2) enough of them have devkits that someone who might not be super vetted has access, and 3) that enough people have devkits that folks feel like they can talk without being hunted down. Which is what has happened with
the Switch 17 months before launch,
the 3DS a year before the launch, it happened to
the Wii a year before launch. It did
not happen with the New 3DS - because there was almost no 3rd party support for the New 3DS at launch, or over its lifetime.
I don't know any credible insiders reporting that a release is imminent, and the manufacturing leaks imply that Nintendo is "dilly dallying." I have my own reasons for believing that Nintendo's hardware production is well ahead of their software lineup.
