As far as I can tell, Spatry is on Hiatus for a little while. He needs a break and will come back when he's good and ready. In the mean time his admins and moderators are in charge of the forums until he's ready to return.
There really isn't a need for new COL videos, not a whole lot has changed other than a few things here and there for Ubuntu and Mint distros. All I know about Manjaro is that GNOME has Wayland by default which is pretty sweet.
Other than that, remain patient.
