This is an unpopular opinion since everybody thinks all 7 of them should debut as they are all very talented(which I agree!) , but I think I am just so sure and certain that they will debut as 7 and all this is just a marketing strategy that I actually want to proven wrong and see what will happen if they end up as 5 if that makes sense. I also think that as a 5 member group, the members will get more opportunity to shine in the group and it will overall more fair for the 5 that will debut and the 2 that wouldn't debut would have one hell of a headstart in the industry and it would be okay for them since they are still very young and have plenty of time to improve and debut.
