Besides which, there is always hope - I am still hoping the Countdown graphic novel is taken into novel continuity so we can have Data back, and I am pretty sure we will see Janeway again at some point...
Considering one is a super android and one was taken by a Q it seems like there are plenty of back doors to being returned. Sci fi is always like that but it's not like the reason has to be added in later, it's there all along in these cases.
