In the months prior to the announcement that Whew was unearthed and headed to Buzzr, Winc.'s YouTube page posted a couple of new-to-us Whew episodes. Haven't seen any new-to-us episodes of Celebrity Sweepstakes...yet. But then again, if some CS episodes pop up, then most of us could guess that they're coming to Buzzr, as now they have tapped Burt Sugarman's shows.
OTOH, GSN still airs Match Game 7x and all the Harvey Feud you can stomach (both Fremantle properties).
Since Sony is sitting on (and not airing) the original Barris NG episodes, perhaps this is a "trade" (Letting Buzzr air Eubanks NG episodes + who knows what else, and Fremantle will continue to let you air old MG & Harvey Feud).
If it is Newlywed Game, I hope they air the 60s-70's eps and not the 80's-90's incarnations -- mostly to mesh better with the majority of their programs that are 40+ years old.
Here is an early 2022 prediction: Buzzr gets the rights from Sony to air Martindale-hosted Tic Tac Dough episodes via trade.or lease (to commence with the NBC airing of Bergeron's TTD reboot).
We'll see...
