That's imposing a linear view of time on things again, when we've already established there is no such thing; there is no 'then', 'now', or 'later', not really. If an Incursion goes to completion, that would mean that a particular universe not only doesn't extend any further into the future, but never did or could. Even if you get into the whole many worlds, alternate futures thing, where all the futures our heroes have visited to, or where Kang and Zarrko and so on came back from, were alternates, those must necessarily be alternates in whose history the Incursion did not complete.
