  The next generation of double-beta decay experiments have an excellent chance
of providing data on the neutrino mass pattern. This presentation is a summary
of what is currently known about the mass pattern and expectations from
experiment. Uncertainties due to the precision in the oscillation parameters
are not critical to the interpretation of a zero-neutrino, double-beta decay
measurement in terms of the mass pattern. Even though there is reason for
optimism, the matrix element uncertainty is still a concern. A selected,
representative group of the future experiments is discussed.
