It is almost certain
that CESR will remain the premier laboratory for studies of
bound states for the next decade.
Potential models describing the quarkonium interaction
have met enormous success in predicting mass splittings in
the heavy 
system. Results from
CESR on the masses and widths of the
vector systems and the masses of
the orbitally excited 
states
have been able to provide direct verification of such
model predictions.
However, the study of spectroscopy is far from complete.
Remaining physics objectives include:
- Measurement of the
-state masses.
- Measurement of the dipion transitions among the
states.
- Measurement of the radiative widths of the
and
states with 
.
- Measurement of the
and 
masses.
- Determination of the partial waves present in the dipion decays of
the
and 
states.
- Observation of two-body radiative decays of the ,
giving information on possible glueball states.
Some of these analyses should yield positive results
using resonant data taken before the upgrade to CLEO III.
Those that do will almost certainly await confirmation from future data sets.
Also, at the higher
luminosities expected for the future, we do not exclude the
possibility that a larger data sample may provide some as yet unanticipated
results. In any case, the future spectroscopy
program at CESR promises to refine our understanding of the
basic quark-antiquark interaction.
