I going to assume that if Pyoro is teasing anything it probably has nothing to do with the Switch 2 or any hardware reveal. It was pretty much confirmed that his info came some sort of eshop backend access. Pyoro had incredibly limited information for the June Direct, mostly third-party stuff, and it's because Nintendo chose to delay putting up eshop pages for bigger announcements instead of having them ready to launch right after the direct. The only games Pyoro did know about and hint at were games that still had eshop pages up and ready to go beforehand (like Ace Attorney Investigations). This also goes for information they had for things like Nintendo World Championships, Everybody 1-2 Switch!, the Sonic Superstars rabbit skin DLC info, and even the Another Code remakes getting a demo - all stuff that would have been uploaded to the eshop and set to go up immediately after their announcements.
Now, after the whole interview nonsense it would be reasonable to assume that Pyoro's source or however they were getting that info would have been plugged up, but there's always the chance that it never actually happened and they just sat low for a while to get eyes off of everything for a bit. Or, maybe there's a new source they've managed to acquire. Or maybe they're just trolling. Who knows? Either way based on their past information I don't know how they'd be aware of an immanent hardware reveal unless there was something about it tied to the eshop.
