BCP3: SUMMARY OF THEORY

I discuss a number of the highlights in theory presented at the BCP3 conference. These included new, and more stringent, CKM fits; a critical overview of heavy hadron lifetimes; progress in computing rates and CP-asymmetries in charmless B-decays; a thorough discussion of the implications of the new results on $\epsilon^{\prime}/\epsilon$; and, finally, a peek at the future, trying to estimate how well one is going to be able to measure the unitarity triangle angles.
