Speaking of "Idol"

Anyone have a guess about what this highly-touted mid-season bombshell is going to be? And why the ever-expanding "Idol" juggernaut thinks it has to change the rules? My best guess, so far, is that they'll take a page from "Project Runway" and bring back a rejected contestant or two -- someone beloved by fans, or perhaps somebody hated. Maybe even a rejected contestant from a previous season.

What else could they do, short of another disastrous movie? "From Taylor to Katharine"...? Yikes.
