The group's tentative name is Pentagon, and according to a music industry insider, the new male group is said to have practiced for years as trainees, although the exact number of members have not been decided yet. If they're going to stick with their group name, we're guessing 5 members?

The music rep stated, "Cube [debuted] the 6 member group B2ST in 2009, 7 member group BTOB in 2012, and after four years they are bringing forth a new boy group. Within the company, they are already known as a 'secret weapon' new project called Pentagon."

Some of the members are said to be talented in composing, and the group Pentagon is reported to debut with a very different concept from the previous two boy groups, B2ST and BTOB.
