We evaluate experimental as well as theoretical uncertainties in this measurement. We find that a measurement of $γ$ with the next generation of B-factories (BaBar, BELLE, CLEO III) is statistics rather than theory limited if soft rescattering effects are small.fixed minor sign error in equation 8 and 11High Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
