  Motivated by the first evidence of the B -> tau nu transition reported by
Belle and by the precise DeltaM_{B_s} measurement by CDF, we analyse these and
other low-energy observables in the framework of the MSSM at large tan(beta).
We show that for heavy squarks and A terms (M_squarks, A_U > 1 TeV) such
scenario has several interesting virtues. It naturally describes: i) a
suppression of BR(B->tau nu) of (10-40)%, ii) a sizable enhancement of
(g-2)_mu, iii) a heavy SM-like Higgs (m_h ~ 120 GeV), iv) small non-standard
effects in DeltaM_{B_s} and BR(B -> X_s gamma) (in agreement with present
observations). The possibilities to find more convincing evidences of such
scenario, with improved data on BR(B -> tau nu), BR(B -> l+ l-) and other
low-energy observables, are briefly discussed.
