Last week Lythgoe had tweeted that there were some surprises in store for viewers. He subsequently elaborated that they would be "shocking, shocking, shocking format changes" -- more of which will apparently be revealed shortly.

Lythgoe has already clarified that the changes do not deal with the So You Think You Can Dancedeparture of judge Mary Murphy or the addition of former American Idol judge Paula Abdul to the panel.
