  Using the most recent determinations of several theoretical and experimental
parameters, we update the Unitarity Triangle analysis in the Standard Model.
The basic experimental constraints come from the measurements of epsilon_k,
Vub/Vcb and Delta m_d, the limit on Delta m_s, and the measurement of the CP
asymmetry in the B sector through the J/psi K^0 channel. In addition we also
include in our analysis the direct determination of sin 2 alpha, gamma and
sin(2 beta + gamma) from the measurements of new CP-violating quantities,
recently coming from the B-Factories. We also discuss the opportunities offered
by improving the precision of the measurements of the various physical
quantities entering in the determination of the Unitarity Triangle parameters.
