The admin of with20star sent in a message to TGN Entertainment regarding the number of members, and more information about their debut. Here's the reply we received.

저희 20star는 20명이 데뷔하는 프로젝트 기획그룹이며, 차후 유닛활동으로 나누어서 활동하는 시스템으로 운영됩니다. 현재 멤버는 18명이 확정되어 연습중에 있습니다. 그리고 많은 분들이 질문해주시는데 노태풍군은 개인사정으로 잠시 팀을 탈퇴한 상태며 , 지금 회사와 차후 활동에 대한 논의중입니다. 20star멤버로 활동을 하게 될지는 아직 확정된바 없으니,자세한 공지가 나오기 전까지는 조금만 양해 부탁드릴게요. 아직 멤버소개에는 모든멤버가 소개되어있지 않습니다. 조만간 올려드리겠습니다

20STAR is planning to debut 20 members, and future activites will be carried out in project groups. Currently, there are 18 confirmed members practicing hard. And to all the questions we have received, 'No Typhoon' has left the team due to personal reasons. The company is currently deciding on his future activites. As of now, all plans are still tentative. Please be patient till further notice. Currently, not all the members have been introduced, but they will be sooner or later.

So yes, this means that they will live up to the name of having 20 stars. A debut date is not confirmed. As well, 노태풍 No Typhoon was a solo artist who came out with his 1st album recently, but supposedly put into 20STAR after that.
