The problem I see is that there will be no more important leaks:
a) Given how around 50% the US population was brainwashed by government and media into believing Snowden is a traitor,
b) Given the fact that America has elected a president who wants Snowden executed,
c) Given that the NSA has locked down their systems completely since Snowden's revelations.
Who would want to take these risks to leak anything just to be put on "the list" by their own country and People?
If Snowden's leaks were not enough to get people thinking then the only thing that will is serious pain and suffering. And that is what I personally expect to come (for the lower and middle class, at least).
