New grand jury = new indictments?

Patrick Fitzgerald has asked for a new grand jury in the CIA leak case, which means (a) he finally has enough evidence to indict Rove; (b) he believes Bob Woodward's revelations could lead to new indictments (Cheney? Bush?), (c) he wants to make sure the case against Libby is watertight, or (d) all of the above.

We're voting for d, all of the above. Final answer.
