I think that was Ryan's thing. So, yeah.
They seemingly stopped doing them after Ryan passed away. I don't think they've done one since. Maybe that was his thing and they didn't want to do one without him out of respect. Just like the Bombcast never misses a week (and is always on a Tuesday (at least somewhere in the world)).
I was mainly being facetious, but I'm pretty sure they stopped doing it even while Ryan was around. It just seemed to drop off when they started outlining upcoming weeks on the Bombcast.
The worst of these "what happened to," for me, would be Random PC Game. Those were always fantastic. Gave us stuff like BioForge and Phantasmagoria
Edit: Huh, now that I think about it, Contradiction was kind of like that in all but its name.
