As indicated by recent data from Tevatron, there might be sizable NP effects in the Bs mixing phase, S_psiphi. We discuss how large values for S_psiphi can be accommodated for in the MSSM. We emphasize that while the MFV framework is not well suited to explain potentially large effects in S_psiphi, models with large flavor changing right handed currents provide natural frameworks to account for such effects and we analyze a specific abelian flavor model where exactly this situation arises. Abelian flavor models naturally realize the alignment mechanism and thus generically predict large NP contributions to D0 - D0bar mixing. We point out that within that class of models, CP violating effects in D0 - D0bar mixing unambiguously imply a lower bound for the EDMs of hadronic systems, like the neutron EDM and the mercury EDM.
