Courtesy of Think Progress, we found the prediction for Arizona Congressman Jeff Flake that we can expect more "earmark indictments":

Over the years, Rep. Jeff Flake (R-AZ) has garnered a reputation as “the House’s No. 1 earmark-hater” due to his willingness “to kill projects” favored by his colleagues. Though he’s gained increased support for his anti-earmark mission since the 2006 elections, Flake says it will probably take “another” earmark-centered “indictment or two” before his fellow lawmakers seriously tackle earmark reform.

Flake believes that day is right around the corner, telling the Politico that he thinks more indictments “are coming“:

One common take on the problem comes from Rep. Jeff Flake (R-Ariz.). The 44-year-old conservative sees many of his colleagues publicly applauding his attempts to kill pork-barrel spending while privately working to keep alive the budget “earmark” system that has already been the wellspring of several recent corruption cases. “It will probably take another indictment or two” to force change, Flake said in a Wednesday interview. “I think those [indictments] are coming.”
