Attention is drawn to the several 2-3 $\sigma$ "anomalies" in B, $B_s$mixings and decays involving CP-observables. Perhaps the most interestingtheoretical scenario that could cause such effects is based on warpedextra-dimensional models and indeed some of the effects were predicted there.However, a rather simple explanation is that based on a fourth family of quarkswith masses in the range of(400 - 600) GeV. The built-in hierarchy of the4$\times$4 mixing matrix is such that the $t'$ readily provides a needed {\itperturbation} ($\approx 15%$) to $\sin 2 \beta$ as measured in $B \to \psi K_s$and simultaneously is the dominant source of CP asymmetry in $B_s \to \psi\phi$. The latter mode is theoretically very clean (unlike the others) andtherefore it would be extremely desirable that Fermilab gives a very highpriority to clarify this anomaly at the earliest. 4th family explanationallows, with relative ease, to accomodate the stringent flavor changingconstraints which usually can be quite challenging for new physicsscenarios.Implications for the LHC are briefly discussed; $t'$ and $b'$ lead tohigh $p_t$ multilepton events, in particular $b'$ decays produce ratherdistinctive same sign leptons with asymmetric energies.
