The historic observation of CP violation in the neutral B
system at BaBar and BELLE this past year is just the first round in
the systematic testing of the CP violating sector of the Standard
Model. Through the study of rare B decays, one hopes to extract the
three unitarity angles alpha, beta and gamma. The current BaBar and
Belle results imply a non-zero value for beta which will be greatly
refined in the coming years. In this talk, I will discuss new ideas
for the measurement of the more difficult parameters alpha and gamma
at B-factories. Although measuring these parameters will require more
luminosity than is currently available, their determination is a key
test of the Standard Model.
