  During last decade a number of detailed analyses of flavour observables and
of their correlations within more than a dozen specific BSM models have been
performed at the TUM. One of the goals of these analyses was to investigate
which model is capable of obtaining large mixing induced CP asymmetry in the
B_s system, S_{psi phi}, and to find out what this would imply for other
flavour observables. In this context also the rare decays B_{s,d}->mu^+ mu^-
have been considered. In some models their branching ratios can be enhanced by
orders of magnitude above the SM expectations. The recent data on S_{psi phi}
and B_{s,d}-> mu^+ mu^- from the LHCb put an end to these very optimistic hopes
modifying significantly the allowed patterns of deviations from SM predictions
for flavour observables in concrete BSM models. We make a first
semi-quantitative assessment of the most important modifications in the
predictions of the BSM models in question including also recently analyzed
models and taking into account the most recent lattice input. For some BSM
models the LHCb data turned out to be a relief. On the other hand the SM,
models with CMFV and MFV models without flavour blind phases appear to have
significant difficulties in describing all Delta F=2 observables in B_{s,d} and
K^0 meson systems simultaneously. We propose to regard the stringent CMFV
relations between various observables as standard candels of flavour physics.
The pattern of deviations from these relations may help in identifying the
correct NP scenario.
