See, the only thing you're overlooking here is that all those links pertain to the assumptions about canon made by StarTrek.com. A lot of fans make the mistake that StarTrek.com is the same entity as Paramount (or now CBS) and that whatever it says about ST is straight from the horse's mouth; but it's actually just a licensee, a promotional website about
ST. So those posts only apply to how StarTrek.com itself chose to categorize the animated series, which is a separate question from how the actual producers of the shows chose to treat it. ST.com's content has been at odds with the producers' view of canon before; it continued to claim that Jeri Taylor's Voyager
were canonical even though Taylor's successors on the VGR writing staff ignored those novels and contradicted Pathways
in multiple respects. And ST.com still claims that Star Trek: The Motion Picture
takes place in 2271, as per the old ST Chronology
, even though it's been years since VGR: "Q2" made it canonical that the 5-year mission ended in 2270, so that TMP (at least two and a half years later) is now generally accepted as occurring in 2273.
And that's the crux of it right there: canon isn't some formal doctrine, it's just whatever the current makers of the franchise choose to count. And that's subject to change as the showrunners change.
Being "on the inside," both at Pocket Books and in the sci-fi tie-in industry at-large, how likely do you think this is to happen? Is the marketability of Star Trek strong enough that TPTB would feel comfortable taking what must be somewhat of a risk?
It is an interesting thought, that Trek tie-ins could follow the precedent of Transformers media and embrace the concept of a multiverse to allow the various different continuities to coexist. We also see similar things in DC and Marvel Comics, which in at least some cases treat the realities of their various film and TV adaptations as parallel worlds within the multiverse (for instance, the Young Justice TV series takes place on DC's Earth-16, and the Marvel Cinematic Universe is Earth-199999 in Marvel's system). And we now do officially have two canonical Star Trek timelines, Prime and Abrams, plus the literary precedent of the Mirror and Myriad Universes series. (I'm not counting alternative prose continuities like the Shatnerverse and Crucible, because those weren't overtly alternate realities, just alternate story directions, and they were still consistent with canon, unlike the possibility we're considering here.)
I have no idea. I'm not that much "on the inside" -- I'm just a freelance writer. The people who'd make that decision are the folks at CBS Licensing, and I've generally only interacted with them through the mediation of my editors. It seems plausible to me, given the fact that there are now two canonical timelines and given how much the books have developed their own identity in the interim (and given that the books weren't required to conform to Star Trek Online
's continuity even though it has a larger audience), that the adoption of an official "tie-in multiverse" approach could happen. But there may be other factors affecting the decision that I can't assess or predict.
