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 epsilonk, Vub/Vcb and Delta md, the limit on Delta ms, and the measurement of the CP asymmetry in the B sector through the J/psi K0 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.
