Very good news, indeed. There seemed to be little reason for AMC to proceed with plans for another season. The ratings were so-so and there wasn't enough of a clamor from the public to expect a renewal.
Hopefully, the entire cast will still be available when shooting begins.
I caught the premiere (and stuck with it) after reading the article in Wired. I enjoyed the season, and am happy it's back. I remember those early days of home PCs fondly. I still have a VIC 20, a TI -99, and an Amiga!
