Success of precision studies in W and Z boson production at the Tevatron and
LHC depends on the progress in reducing theoretical uncertainties to the level
of 1-2%. I review recent developments in theoretical understanding of W and Z
boson production and remaining issues to be solved to meet demands of the
near-future experiments.Comment: Contribution to the proceedings of the 15th Topical Conference on
Hadron Collider Physics (HCP 2004, June 14-18, 2004, East Lansing, MI); 14
