"Merry Christmas from all of us at Roseanne," Barr says in the short clip. "The original cast is coming back with all new episodes in 2018. It's the gift you all asked for!"
"Did they ask for that?" Goodman asks.
"No, but we're doing it anyway," Barr replies.
The clip gives yet another look at the set, which perfectly replicates the iconic Conner family living room from the original series.
Sara Gilbert is back as Darlene, Lecy Goranson is back as Becky and Michael Fishman will play DJ again. Laurie Metcalf is back as Roseanne's sister Jackie, and Johnny Galecki will play Darlene's husband (formerly boyfriend) David again.
Sarah Chalke, who played Becky in some episodes of the series, will play a different role.
Estelle Parsons, Sandra Bernhard, James Pickens Jr., Natalie West and Adilah Barnes will also be back.
New faces include Back to the Future legend Christopher Lloyd, Shameless' Emma Kenny and Jayden Rey.
One character not expecting to come back is Mark, David's older brother. The late Glenn Quinn played the role on the original series and the producers don't plan on recasting the role.
Roseanne returns to TV after a 20-year absence on Tuesday, March 27 at 8 p.m. ET on ABC. The new season runs nine episodes, including a one-hour premiere.
