I mean, a lot of it is likely "diagnosable hyperfixation" as much as it is anything like skill. But it's basically Google + Contacts + an unusual background. I have had a winding tech career, and art career, that gives me surface knowledge of a lot of things. Which feeds back into the first two.
As an example, I think it was
@darthdiablo some months who very smartly suggested you could look at casting calls, and see if someone was developing an ad for the next hardware. Google turned up a couple of tantalizing possibilities, and they were being discussed here.
I work as an actor, so I know that there are only so many casting-call databases and I already have paid memberships at the biggest ones. I checked all of them, but I also reached out to some production company friends who might have access to calls for camera/makeup/lighting crew. The Switch October ad was produced with non-union talent and shot in Canada, which is not uncommon when you want a wide variety of non-actors, with a wide-variety of looks. But the crews are almost always union folks flown in from LA or NYC.
So I pinged all my game nerd buddies and asked for anything that might match on any boards they might check. I got maybe 20 ads, filtered out the obvious ones. Then, for the ones that were left, I asked some game industry friends "hey, this is how a project is being described. Do you know anything unannounced-but-common-knowledge that might match?" Like, the one ad that looked like it might match turned out to be a print spread (non-video) for the most recent Atari Flashback.
With Samsung, I don't know anyone who works there. I know several people who work
with them, so I can ask questions like "what does this internal four letter acronym mean" and "would this project come out of Samsung Korea, or not." That's how I determined it was two separate projects. They looked like the same project from google, but two people claimed to be managers, in two different countries. Asked around, ah, separate branches. One usually does work around automotive (unsurprising, considering the origin of Orin/Drake), the other is strictly storage related.
