  We study the impact on the unitarity triangle of the Bs-bar{Bs} 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 mB_s recently reported by DO along with the first
measurement achieved by CDF, Delta mB_s=(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.
