Most of them seem to be correct. Apple Car was basically an open secret for years before it was cancelled, same with AirPower and even Apple Vision Pro had it's price estimate leaked before it was announced.
It feels like Apple thinks they're really good at hiding stuff, but forget that their employees love to talk. Nobody will forget the prototype iPhone left just sitting there unattended at a bar.
AirPower was actually announced. The problem with the others is it’s hard to know which are intended to be products or research. Particularly items that are far from any sort of release.
For example, I’m skeptical that Apple ever intended to release a car.
