On the Famicast Twitter page, it showed a screencap at the 4:55 mark of Takashi Tezuka at the Zelda booth, with the gang walking by him unaware (as pointed out by a YouTube viewer). So I watched the video with that in mind. JC turns the camera from the Splatoon 2 demo and at 4:20, Tezuka walks into view in front of JC, passes directly in front of Danny, then you guys walk behind and pass him as shown in the screen cap. Then at 5:29 you see Tezuka talking with a tall man who's making big gestures (perhaps, OMG Takashi Tezuka!).
It would have been better if the tall man had been Ty, then only after the video had been published would he have said, "Oh, hey guys, guess who I met at the Switch Event." "WHAT?!?"
Only just started listening to the episode, so can't comment on it, but wanted to mention the Tezuka sighting on the forums.
