Some more info about the coming weeks of K-Pop Star.

On the next three episodes we will be seeing a "battle audition" for the top 10 spots. After being trained further the contestants will compete as representatives of the company they were cast by during the final casting audition from the last two weeks. They're going to face off against one another and will be ranked. The contestants who come in first place will be automatically qualified while the contestants who come in third place are eliminated. The contestants who come in second place will have additional 1:1 performances and are only partially qualified, since two more contestants will have to be cut.
Live broadcasts will begin on March 4th after the final 10 are chosen. They originally wanted to begin the live broadcasts on the 26th, but moved it back a week because there was too much content from the battle auditions that they didn't want to edit out. Once we get to the live broadcasts, one contestant will be eliminated each week until the winner is chosen on the last week of April. Viewers will be able to vote for the contestants via text and the staff is currently deciding on how much the viewer votes will count towards the final decisions, although they have already announced that it will not count for more than 40%.
Also, they're currently thinking favorably about releasing songs from the top 10 contestants' performances through music sites.
