Thanks for the info, Johnny. I did not know they changed the age groupings. Makes sense, though, because they have some very talented youngsters this year.
They didn't say last year how it was decided who got which group. I'm guessing they won't say this year again. And I'd have to assume LA got over his disappointment over his assignment, or there probably would have been rumors about him being replaced.
The eye patch girl is solo, but they could have put her in a group like they did with other soloists last year who didn't make the cut alone. I was only speculating that she was in the "groups" group.
FWIW, the very popular group One Direction was an assembled group of soloists from Britain's X-Factor show.
