The old video was available for everyone to watch until Tuesday; I suspect the new video was just them wanting to clean it up a bit for the proper episode release. For instance, at a bit of a skim, I feel like the intro music vid now looks sleekly edited in versus "being viewed on Christopher's PC".
FWIW, here's a few of the exciting reveals! I mentioned, stealing from WT's crib notes:
"Zhu Long has weird, inscrutable plans all over the world. Christopher: 'Of course, there is the fact that Rook City has an underground component that is a very magical sort of realm. Don’t worry about that'.”
"Does the planned tie-in RPG One-Shot for the Sentinels of Freedom video game cover the same story as that game or is it its own thing? The Starter Kit, other One-Shots, and detail in the core book establish a set of facts about the world. This adventure will connect some of the dots between those things and the SoF game (which is now available on Switch - there’s a Sentinel Comics property on a Nintendo console; how awesome is that!) but it’s not necessary to have played SoF to understand the adventure."
"How’s the story coming along for Chapter 2 of Sentinels of Freedom? It’s done. Underbite’s had it for a while now."
"You’ve said previously that you had written up a lot of story for Underbite’s Sentinels of Freedom game, but they had to chunk it up into Chapters. We’ve now had a chance to see how long Chapter 1 was and they’ve talked about Chapter 2. How many Chapters would you guess the original story you wrote for them would take to cover? Chapter 2 finishes that original block of story. There are a few side missions that ran long and will wind up falling outside of Chapter 2, though."
"As someone raised on 90’s cartoons, and who recently made jokes about PSAs with one of his SCRPG characters, I have to ask: What is your favorite ham-fisted, cheesy Sentinel Comics 'Don’t play with drugs/guns/alcohol/strangers/Halloween candy with razor blades on them' PSA? There’s one that’s coming up in Chapter 2 of the Sentinels of Freedom game. Or maybe it’s more of an advertisement than a PSA. Anyway, you’ll see it there."
"Can you tell us about the British and French heroes from the 'Heroes of Yesterday' banner pictured alongside Grandpa Legacy and G.I. Bunker? Their names are Tommy Atkins and La Louve, but they’re not going to tell us more about them here."
"Yes or No - Is there any future Scholar content even if it's Scholar in the past? Actually yes!"
