I have just read this quote below and it seems that there will be a lot of problems if they dont find the Higgs boson, there is also no reason to think that it wont be foud with higher energies.
<FONT COLOR=blue> "The Higgs field and its quantum the Higgs particle are used in the Standard Model to give mass to the W+, W- and Z0 weak bosons. Without it the theory would predict that these particles had zero mass. But their masses are a matter of experimental fact, so without the Higgs, present day explanations of what happen in the accelerators falls apart."</font>
