We discuss polarization in charmless B->VV decays, and the importance of
penguin annihilation power corrections for reproducing the phi K* data.
The sensitivity of polarization measurements to new RH currents, and
information about new physics that can be obtained by comparing CP
violation in different transversity modes is also addressed. Finally, we
discuss how we can learn from  continuum e+e- -> M1 M2 measurements
about the importance of annihilation power corrections in rare B
decays. We discuss CLEO-c data at sqrt{s} near 3.7 GeV, and the
importance of measurements at larger sqrt{s} at the B factories using
radiative return, and measurments at the Upsilon (4S).
