believe the person(s) leaking must be close to the investigation and want to see an indictment on some charges, even if it is only perjury or obstruction of justice. Fitzgerald is probably leaning against indictment and the leaker wants to create a public expectation in order to try to pressure Fitzgerald to file charges.

Or, build up a huge expectation, likely knowing nothing will come of it. If Fritzgerald builds a case that revolves around a perceived cover up and not a TRUE outing of an undercover agent this will be the laughing stock indictment of the century only second to Delay's B.S. indictment.

If anyone seems to be lying about anything it's Wilson.

That doesn't make sense as a motive at all.
These leaks do not help Rove in any way.
Should the investigation end without indictment, many partisans will feel that justice was not served, especially after getting pumped up by reports that indictments are in the works. With the conspiratorial mindset of the typical leftwing nutjob, one can only imagine what rumors will be floating around as to why no one got indicted in the end.

The only plausible motive for the rumors is that someone is trying create momentum in the public for an indictment in order to make Fitzgerald feel obligated to being some.
