SNW continues to present a take incompatible with pre-streaming novels
There isn't really an overarching TOS-era continuity the way there was with the 24th-century novels. There are some things that have continuity within themselves and reference other TOS-era stuff, like
Vanguard and my TOS-era books, but a lot of the books are standalones.
And most of the novels that featured Pike and Number One weren't really part of any larger continuity anyway. I'm not sure there are any that overtly connect to the larger Novelverse.
James T. Kirk
SNW continues to present a take incompatible with pre-streaming novels
The only version of Kirk we've seen in SNW to date is from an alternate future. His season 2 appearances seem likely to introduce inconsistencies, though.
Gary Seven's organisation
PIC tying in Wesley Crusher's Travellers is incompatible with previous novels' depiction of the Aegis programme
As I already said, this is not the case. There's no reason the Aegis as depicted in the novels couldn't
include the Travelers among its participants.
Khan Noonien Singh
PIC and SNW have implicitly set up a future arc or series incompatible with all previous works, instead implying Khan Noonien Singh as born in 1996 and participating in a second Eugenics War
This is incorrect. The files that Adam Soong examined at the end of PIC season 2 were dated 1996 and titled "Project Khan." There is no reason a project involving the Augments' initial conception would be named for Khan specifically, since he was just one of hundreds, and nobody could have known at his conception that he would be the most successful or dominant one. The only way "Project Khan" makes sense was if it was a project commissioned
after the Eugenics Wars to attempt to replicate the Augments. We already know from
Enterprise that the Soong family does continue the Augment project on its own in future generations.
Andorians
Undetermined as of yet; DIS et al. continue to virtually ignore the novels' four-gender system
Everyone seems to forget that the four-gender system in the novels was designed from the start to be compatible with an onscreen two-gender portrayal of the Andorians, with two of the genders presenting as male and using he/him pronouns in English and the other two presenting as female and using she/her pronouns. The creators of the books' system
knew that the shows would likely continue to portray Andorians as two-gendered, so they pre-emptively designed a four-gender system that was reconcilable with that.
SNW may yet go differently compared to previous novels' depiction of the near-extinction of the Aenar
The novels establish that the Aenar's apparent extinction doesn't happen until the late 2270s, a couple of decades after the SNW time frame.
Gorn
SNW's take is utterly incompatible with pre-streaming novels
And with "Arena." I prefer to believe SNW's "Gorn" are a different species entirely, perhaps some kind of Gorn bioweapon animals that have been mistaken for the actual Gorn.
Klingons
DIS and SNW ignore the existence of the QuchHa'
That's no worse a problem than TOS not having any HemQuch, or TNG not having any smooth-browed Romulans. In many such cases, we simply have to assume that they were there, but just offscreen. It's a big universe and we only see a narrow piece of it at any given time.
, have a different background for human-looking infiltrators,
No reason all infiltrators have to have the same origin.
and set up a different backstory for Klingon escalation in the 2260s
I don't see how.
Mirror Universe
DIS's depiction of Emperor Georgiou is, of course, utterly incompatible with pre-streaming novels
I don't think so. The Novelverse MU continuity conveniently skips over the period from 2248-2264, aside from one brief flashback to the Mirror version of "The Cage," which reveals little about the state of Imperial politics at the time. So there's room for Georgiou's stint as Emperor to be plugged into the continuity, if you gloss over a few details.
