If they keep trickling out it will be a long time before "we" (i.e. the media, and probably a lot more people than are willing to admit it) lose interest, if there was a mass release of info then we'll lose interest, it'll be another "so what?" revelation. But even then, I imagine a few years would then pass and there'd be some renewed interest.
Nah, about 15 years ago there was a glut of revelations about Tory politicians. The fact that every second MP seemed to shagging someone he or she shouldn't didn't stop the front page headlines, nor the interest. We're still making jokes about some of them today.
