Right now, all we know is that it'll allow someone to 'overthrow the HoH'. And that's assuming Julie was reading her cue cards correctly, which is never a safe assumption with someone who can mix up Diane and Danielle during a live vote. So a few of the obvious questions are:

1. How do you get it? Competition? Clue given to all the hamsters, and the first one who finds the backstab dagger hidden in the cage gets the power? Can the HoH compete for it to stay safe?

2. How often? I don't think this can be a weekly event, just because it's too much chaos for too little airtime. Once during the season, possibly. Three times, tops.

3. When do you use it? Right after the HoH competition? (You can't use it beforehand to make yourself the automatic winner, or 'overthrow' doesn't come into play.) Before nominations? After nominations? Just before the vote? After the vote?

4. What does the twist do to the nominations? Can the overthrower place their own nominations on the block after the original HoH already did? If the power is used from the block, does it send the old HoH there in the new person's place? (I think this is likely -- a veto with extra teeth. Former heads of state never do well in this kind of thing.) Is the new HoH stuck with the old one's picks?

5. Will this actually have an effect on gameplay, or is this the latest in a long line of BB non-twists?

Theories?
