And the Lockdown arc will probably resolve with the overall CFD storyline, which can't resolve until there is some way of either restoring older personalities rewritten, or coming to terms with the rewriting. If it does involve using the Deep Resonance to restore their personality (creating and implanting an e-ghost over the intruding AI?) then only beings who left a deep imprint on the Matrix have much of a chance to come back. At minimum I expect FastJack to reappear because of it, and it'd be nice if they paid off the bit at the end of System Crash with Captain Chaos' e-ghost.
Be interesting if CC's e-ghost or FastJack, is planned to be one of the major NPCs of a later Chronicles story, and that's why CGL can't do drek until Chronicles either wraps up or is canceled; be a shame if CGL dropped major spoilers for another company's game, ne?
