Quote from Warren Spector via the Otherside forum:
We parted ways with Starbreeze (amicably), which means we are in the process of lining up a new publishing partner. Happily, given the pedigree of System Shock and the progress we’ve made so far there’s been a lot of interest. Has the situation affected development? Not really. The team is still, as we say, ‘psyched and cranking’ - in other words, continuing as normal. We’re confident we can bring System Shock 3 to market and have it take its place as a leading title in the immersive simulation genre.
