gumbo - the impression i got was that the 4 groups had NOTHING to do with talent - they simply want to break you down into more easily-managable numbers. it's not like a "group 1 and 2 will definitely move on" thing...i think it's just a "it's a lot easier to deal with 13 people at once than 52, so let's talk to group 1 now."
that said, i could be wrong. but the four groups seem to be just a management system, NOT part of their re-audition system.
did that make more sense?
