He retired the format a few years ago. Now he just does game shows and random projects with his friends, which...fair enough, that's what I'd do with a pile of passive YouTube income.
He recently did one of those "this video will delete in X hours" bits where he asked people to email him different places, people, things to check out.
He very, very clearly has no interest in returning to weekly videos on-location; more deeper dives or just something different.
