He's not even really gone. He's just not doing 52 videos a year, on the regular.

Presumably his next release will be circa February. Just a wild guess for enjoying a long-anticipated break. Then I'd expect another 20-odd videos this year, distributed basically at random.

Not counting videos that are just him and the squad, which will hopefully come back in style. Citation Needed videos are fantastic. Four people with wildly different areas of expertise, who've known each other for ages, faffing about on-camera.
