If he can, but does not want to, he is wicked. ... If, as they say, God can abolish evil, and God really wants to do it, why is there evil in the world?" -Epicurus
Fear is the mother of all gods.
Nature does all things spontaneously, by herself, without the meddling of the gods. -Lucretius
Dave has said on alt.books.david-weber that there will be at least two more of that series, and that the first one will most likely be a prequel, beginning a few hours before the mutiny and following Nergal's crew up until the time of Mutineers Moon. The second, of course, follows the final war against the Achuultani.
I'm afraid it's no more than an omnibus edition of the first three novels. The good news is it means that there are very likely more Imperium novels on the way soon. If they are bothering to release an omnibus it's a good indicationn that Baen and/or David want to raise the profile of the Imperium trilogy since it's rather hard to find.
