I suppose so....
Though I would assume the editorship would have immediate future storylines for DS9 and VOY already mapped out, and that various characters from said series could still make appearances without revealing any significant plot threads from their respective books???
Why would you assume that, when it's the very same editors who worked for over a year with Dave on Destiny
, and made certain there was minimal use of those characters?
Remember, too, that the "immediate future storylines" for DS9 are still some four years behind Destiny
, and that the "immediate future storylines" for VOY is getting its own big thick novel in just a few more months.
