His Friday news conference comes as an independent investigative report on Jae Su Chun is scheduled to be released.
The 20-year-old Cho told reporters Sunday he expects to be suspended or banned because of tampering allegations but declined to say if they were true.
The allegations are part of a scandal involving U.S. coach Chun, accused in a demand for arbitration of ordering Cho to sabotage Jean's skates. A dozen national team members also have accused Chun of verbal, physical and psychological abuse.
Chun has denied all allegations but is suspended.
