There is a big difference. The experiments showed that the ether didn’t exist. But there is no experiment that shows that there is no Higgs boson. IIRC the expected roadmap is to find the Higgs boson in 3-5 years (from now) in the LHC, so don’t expect to see it sooner. (It is expected to see it in sooner in 2-3 years in the Tevatron, if it were kept open.)
The experiments show that if the Higgs boson exists, it is not very heavy (not heavier than 145GeV). And there is some indirect and inconclusive evidence that it exist and the real mass is near ~120GeV (probably +-10GeV), but it can be a statistical fluke, so we have to wait a few years.
