'God particle' may not exist if no evidence found before 2013

If the Large Hadron Collider does not prove the existence of the Higgs boson in the next two years, physicists say the entire Standard Model theory of subatomic structure must be reassessed.

The announcement, made at the American Association for the Advancement of Science meeting on 21 February, 2011, comes as the CERN nuclear research team in Geneva reveals that the temporary closure of the particle accelerator for maintainence will be put off an extra year, until the end of 2012.
By the end of next year, we hope very much that we will be able to say something about the Higgs," said Felicitas Pauss, head of international relations at CERN.

However the team are aware that what they find may not be what they were looking for.
"We know the Standard Model is wrong at some level," said Thomas LeCompte, physicist and coordinator for the LHC's ATLAS detector. "We know that something lies beyond that. The Higgs is the simplest and most elegant way to push it to the next level, but nature may have something else in mind."

Or is it too closely tied to the Standard Model?

At least according to Wikipedia. Apparently his theory predicts up to 22 particles that might be found at LHC and also predicts no supersymmetry, so I'd guess that not finding the Higgs is problematic for Lisi (though perhaps his Higgs can have a larger mass?). It also sounds as if there will be many chances for his idea to be proven right or wrong as LHC collects more data.
