This isn't Doctor Who. As I said, Destiny was not meant to be a fakeout, and frankly I think it's unfair to Dave to treat it as though it was, as though the massive impact it had on the Trek universe is something you can just wave away as a temporary aberration.
Frankly, that assumes the value of Destiny as "the End of the Borg" outweighs the value that would come from their return story. In the end, it's all about the presentation and the value of the story.
You can safely assume that nobody associated with the current Trek Lit continuity is ever going to associate the Borg with V'Ger. Destiny pretty definitively established there was no connection between them, even aside from the fact that it should be obvious that they have nothing in common. And what I established in Ex Machina and The Buried Age about the post-TMP journey of the V'Ger/Decker/Ilia entity is completely incompatible with the notion of it having any interest in recreating the Borg.
So noted.
First off, the Romulans were never "under" Nero. He wasn't their ruler, he was just the captain of a single ship.
Yes, he was the first Romulan villain in a long time and a very effective one as the Captain of a ship and a terrorist as opposed to that of a nation state.
And second, of course he exists in the Prime reality. That's where he came from in the first place. It's just that he leaves the Prime reality in 2387 along with Spock and spends the rest of his life in an alternate reality. But he was born and grew up in the Prime reality.
Yes, but he evacuated to Star Trek Universe-2 (or whatever we're calling it) with Spock. So, he no longer exists in the Star Trek universe. I think we were just having a miscommunication.
Unfortunatly you can count me as being among those who expect a return. Not by the current editors and authors but you never know what will happen in the future. One day somebody will decide that the Borg will return and that will be that. They're a well known Trek villian and it's invevitable that they will be back in some form.
I also wouldn't be surprised to see Anna Sandesjo back at some point. As they say in the comics, we never saw the body. Not saying that one will happen, just wouldn't be surpised if it did.
To be fair, I understand people who don't want the Star Trek Expanded Universe's "Big Crisis" invalidated. Also, it's a very rare resurrection that is done right. "The Search for Spock" is about the only time in fiction I've ever really seen it done well and maybe the return of Jean Grey.
The first one.
Really, I think the Borg are sort of overused as a concept. I think Voyager overused them. I think that anytime someone has a neat bit of unanswered Star Trek lore and they go "The Borg did it" it's a bad idea. Really, I applaud Lit for making the evil "Brain Bugs" to be evil Trill.
God knows, I dreaded the possibility of the Temporal Cold War being about the Borg.
I do, however, think that destroying the Borg was a mistake. No matter how awesome Star Trek Destiny is, you shouldn't break the toys you take out of the Star Trek toy chest. You should play with them, pose them, and put them back in the toy chest the way you found them unless you are:
1. The creator of the toys.
2. Your change will open new story avenues.
3. The death you give them is SO AWESOME that it is better than any new stories that can be told with them.
