Perhaps quantum computers will help break the deadlock? They'll make it possible to extrapolate the consequences of theories that were previously intractable. This might mean that a large number of candidate theories could be tested wholesale to see of they match existing evidence. In particular I know that it's currently very hard to get predictions from quantum chromodynamics, which means that the standard model hasn't yet been fully tested.
