With allegations of sexual misconduct spanning five decades from more than 50 women, it was only this past week that Bill Cosby was criminally charged for the first time and ordered to appear in a Pennsylvania court room. Elizabeth Vargas brings the latest news from the front in "The New Cosby Wars" - a legal battleground that now includes both civil and criminal actions across several jurisdictions - including Cosby's new defamation counterclaims against some of his accusers.

Saturday night, "20/20" updates the A&E documentary "Cosby: The Women Speak," produced by ABC's Lincoln Square Productions. It is a dramatic and provocative show offering intimate interviews with 10 of Bill Cosby's accusers, detailing their stories and claims of victimization by the legendary comedian and actor.

"The New Cosby Wars" airs on "20/20 Saturday," JANUARY 9 (10:00-11:00 p.m. EST) on ABC.

"20/20 Saturday" is anchored by Elizabeth Vargas and David Muir. David Sloan is senior executive producer.
