Well in some ways AOA is at a career spot where winning might be most important to them. They have shed some members and are at that career point where many groups tend to fade even if they stay together. Winning might boost them for a few extra years. Likewise Lovelyz should be pretty hungry too as they are at a point where they really need to break out. Park Bom could certainly benefit from a good showing. G-Idle could boost their career a little further with a win. Mamamoo is obviously the prohibitive favorite as they are hard to beat when it comes to live singing and showmanship on a live stage. That said they don't need this. I suspect they are doing this as much for the challenge and fun of doing it than trying to win. Oh My Girl is probably a close second to Mamamoo. They have some excellent live performers and are really coming into their own as performers. I wish there was more info about how this show will be formatted. For instance must they self-compose and arrange, do they get assigned material randomly, do they have to win some kind of mission to pick material first, second, third, etc. Also Mnet needs to have any voting by fans or judges to be very transparent. Netizens will be heavily scrutinizing the voting looking for evidence of rigging by Mnet after the Produce and Idol School revelations that have been in the news. Mnet owes it to these groups that a winner doesn't have a cloud hanging over their head due to suspect voting.

Does anyone know how the winners will be decided? Hope its not simple voting coz that'll just go with fandom size. Maybe if its based on 'ice-skating style' scoring (0-100); eg. remove 10% highest & lowest scores, and average the rest.

At least that might level the playing field for all groups.
