  Surveying known hadronic rare B decays, we find that the factorization
approximation can give a coherent account of $K\pi$, $\pi\pi$ and $\rho^0\pi^+$
data and give predictions for $\omega^0\pi^+$, $\rho\pi$ and $K^*\pi$ modes,
{\it if ${Re}V_{ub}$ is taken as negative} (in standard phase convention)
rather than positive. As further confirmation, we expect a lower $\sin2\beta$
value at B Factories as compared to current fits, and $B_s$ mixing close to LEP
bounds at SLD and CDF.
