We estimate, in a large class of scenarios, the sensitivity to new physics in Bd and Bs mixings achievable with 50??ab-1 of Belle II and 50 fb-1 of LHCb data. We find that current limits on new physics contributions in both Bd,s systems can be improved by a factor of ~5 for all values of the CP-violating phases, corresponding to over a factor of 2 increase in the scale of new physics probed. Assuming the same suppressions by Cabbibo-Kobayashi-Maskawa matrix elements as those of the standard model box diagrams, the scale probed will be about 20 TeV for tree-level new physics contributions, and about 2 TeV for new physics arising at one loop. We also explore the future sensitivity to new physics in K mixing. Implications for generic new physics and for various specific scenarios, such as minimal flavor violation, light third-generation dominated flavor violation, or U(2) flavor models are studied.
