As one of the aforementioned malcontents, I'm of mixed opinion here.
I'm glad to have finally gotten the Voss and Tempest episodes; as core-set characters (and with how often the Voss invasion has been referenced in episodes dating well back to the Legacy ep.), they have a pretty big impact on the multiverse. Ironically enough, Tempest was the very first Sentinels character I played... (during which my wife and I got pasted by Plague Rat).
I'm perfectly fine with the OblivAeon episodes being delayed until we've had a chance to pore over all those cards. That makes sense to me and C&A were very up front about saying, "We could do this in May/June as they're arriving, but you're not going to have context, and you're not going to be able to ask all the awesome questions you have been." We see precedent for that line of thinking with the Fort Adamant and Plavu'Col environment episode sections, which were significantly lacking questions.
I guess, in retrospect, I would have probably (and this is me personally; I'm not speaking for anyone else) tried to own up to/rectify the overall timeline earlier. Or, for that matter, at least say something about it. For us to arrive at Episode 50-some, only to find out, "Yeahhh, we messed up some of the things we've already told you..." only exacerbates the problem.
I'm still of the mind that Voss isn't gone, despite the "There is no future for Grand Warlord Voss." While this might technically be true if Voss is REDACTED and dies fighting the heroes during the OblivAeon crisis--the future sections deal with stuff post-OblivAeon, so it's technically "true-ish"--it's still properly misleading. This goes doubly, having listened to today's Editor's Note, wherein Christopher mentions at length how many times the heroes watched Voss die, "That mothership just blew up; nothing survived that!" While I really like the idea of Voss as a scion of OblivAeon, it does feel a little cheap to come back in May/June and say, "Oh, well we only said there's no future for Grand Warlord Voss. Rainek Kel-Voss, Scion of OblivAeon, is another story..." While my curiousity would have been piqued, I would have been perfectly satisfied with a future section that was simply, "You haven't seen the last of Rainek Kel-Voss."
Granted, that may not be the case--if I'm wrong about REDACTED, I'll be both shocked and intregued--but it feels a little extra disingenuous to have this podcast full of lies be piled with lies about the lies that we were lied to about.
Long story short: I liked it the ep. I wish it had come earlier, but understand that the actual SC timeline had some issues. I wish those issues were revealed/rectified earlier (as I'm sure C&A do as well). I still think REDACTED is Voss. I do wish there was at least a vague admission of plans with Voss in the future, regardless of what those plans are.
