  Exciting results from the Relativistic Heavy Ion Collider (RHIC) have been
presented at this Workshop. However, fundamental questions remain to be
addressed in the future regarding whether the system is deconfined, chiral
symmetry is restored, a color glass condensate exists in the initial state, and
how the system evolves through eventual hadronization. Jets, heavy flavors and
electromagnetic probes are sensitive to the initial high density stage of RHIC
collisions, and should provide new insight. Significant additional capabilities
will be added with a luminosity upgrade of RHIC (to RHIC II), upgrades of
present detectors and a possible, new comprehensive detector at RHIC II.
