As far as I can tell there is no or not much data from experiments that contradicts existing theories or is unexplained. It is of course worthwhile to probe theories in currently unexplored territories but this is getting more and more expensive. No unexplained data, no new theories based on that. Our current problem is just that we don't completely understand our theories and how they fit together. So unless we are lucky and find some important new experimental data, supersymmetric particles for example, there is not much we can do besides reformulating our theories and looking at them from all possible angles until somebody sees something nobody ever saw before.
