When there are 12 guys & 12 girls those shows have always been pretaped. This is nothing new, they were Live only for Seasons 8 & 9, to the best of my memory. Supposedly the results are still going to be an hour. And getting rid of the guest mentors, to me, is a great thing. What did Miley Cyrus & for that matter Adam LAmbert add to the proceedings. Jimmy Iovine is a permanent mentor this year. He has a world of knowledge & a huge resume. I think all these changes, including the judges, that redefined the show in a positive way.
