Interesting. I read in Science magazine that the physicists are in fact worried about the LHC. Their concern is mainly that they will find ONLY the Higgs boson, and no other new particles. That will effectively wrap it up for the Standard Model of particle physics, and there's nothing more for them to do. They feel they'd be better off if they DON'T find the Higgs, as then they will have a LOT of work to do to their Model.
It takes all sorts.
