Ha! That would be a much bigger headline. Well, in a sense, its already been detected, but just not directly detected in a lab, produced by the LHC, or observed via any self-annihilation process. We know something it exists through cosmological observations - so in that sense its been found.
.. having said that, there are a few experiments that have data which some have claimed or interpreted as direct evidence for dark matter. but the community is far from agreement on that. in fact, most people are skeptical.
