Future of B physics at CDF and DOe

In this contribution to the panel discussion on 'The Future of Hadron B Experiments' held at the 8th International Conference on B Physics at Hadron Machines (Beauty 2002) at Santiago de Compostela, Spain, June 17-21, 2002, we explore the physics potential for B physics at CDF and DOe in five years and beyond. After a brief introduction to precision flavour physics, we concentrate our discussion on the future of CP violation by evaluating the prospects for measuring the CKM angles β, γ and α at the Tevatron Collider experiments CDF and DOe by the end of Run II
