Don't forget, David Mack, and Dayton Ward I believe (or was it James Swallow, I forget) have told us all to relax, they have a plan for all this

.
I've gone back and forth on the whole litverse thing with the new Picard show coming out. At one time I was thinking if they just retained Rene, the destruction of the Borg and not focus too much on the past, most of the novel lines could continue in some form or another. Then pessimism that it was basically all going to be wiped out and the relaunches would end at that point. Now I would say I'm at a more realistic place.
There may be some storylines that could continue. We do know the show runners have at least reviewed some tie-in information (which by itself is a big step from past producers who basically ignored tie-ins for the most part). But there are other tie-ins of course, including comics for instance. But it's possible they decide to build off a story line or two from the litverse if it serves their ends. Perhaps, for instance, there's something from the whole Section 31 storyline they decide to work off of. We assume, probably with good reason, that something during Romulus' destruction has a profound effect on Picard. However, that does not mean that's the only thing that has an effect on his current situation in the show. Perhaps it's the Section 31 angle AND something that happened during Romulus' destruction (and perhaps other things as well). I'm just speculating of course, on a way something from the litverse could be continued.
I am very curious to read "Collateral Damage". David Mack, is, after all, the one who said they have a "plan." And based on some of his later comments I don't think that was simply tongue in cheek. I'm not expecting "Collateral Damage" to be significantly tied to Picard, but I have to admit I'm curious to see if his new novel has any hints, not only hints about "Picard" but hints about what that plan might entail. I do find it interesting also that the novel cover reverted to the original TV show logo instead of the relaunch logo (which I admit bugs my OCD since I have all my TNG novels in order and this one will appear differently--I kind of wish if they were going to do that they would have started with "Available Light" since that was the first trade TNG relaunch novel....but I digress). But I get the impression they reverted to that logo because they don't just want us followers of the relaunches to buy it, but old fans of TNG that are excited about a follow up show. Fans that might buy the book thinking it may give them some world building toward the new show, however minor. I mean, of course it's possible they're just capitalizing on the new show but I'd be surprised if there is absolutely nothing that ties this novel to the upcoming show in any way.
Now, I am still pessimistic about every seeing any more DS9 or Enterprise books (or Voyager books after "To Lose the Earth" comes out). And I'm not sure we'll get any actual TNG books after "Collateral Damage". I have a feeling they'll switch them to Picard books and be more focused on tying into that show. Though I continue to hope the existing novelverse at least takes us to the destruction of Romulus and how that reorients the various allies of the Khitomer Accords and Typhon Pact.
