Re: TNG: The Body Electric by David Mack Review Thread (Spoilers!)
I doubt that this will be the last we see of Data. I haven't gotten to the CE books yet, so I don't know his exact situation at the end, but I find it hard they would bring back a character as popular as Data, and not continue to use him. I could see him being downgraded to a recurring character, but I don't see him disappearing entirely.
