We study the impact on the unitarity triangle of the Bs-barBs flavor oscillation data analyses being carried out at the Tevatron Run II. In the current version of this work we consider the first direct experimental bound on the mass difference Delta mBs recently reported by DO along with the first measurement achieved by CDF, Delta mBs=(17.33 + - 0.4) ps-1. In particular we show how these measurements further constrain the compatibility between the experimental value of sin(2beta)exp.=(0.591,0.783) at 99% C.L. and the value obtained by the fit of the CKM parameters considering just CP conserving experimental observables: sin(2beta)CP-conserv.=(0.742,0.856) at 99% C.L. We also obtain bounds on certain classes of processes beyond the SM.
