Crystal Ball Session: Predicting Future Science Policy Crackups

This is a very open ended post. I'm interested in a little futurism--and some feedback from all of you. Let's postulate, shall we, that the next president does in some sense "resolve" our two current hottest science policy controversies--stem cells and global warming. Then, the question is, what's next? What topics at the science policy interface will all the talking heads be shouting about during the next presidency? Nanotech? Genetic engineering? Something on nobody's radar? To answer this question, I think we need to bring out the crystal balls--the long range forecasts. To me, the only obvious thing is that there will continue to be these flare ups along what is now well established to be a very active fault line. But exactly where along that fault...that I'm not sure.
