  We present predictions for the total top-quark pair production cross section
at the Tevatron and the LHC with 7,8 and 14 TeV centre-of-mass energy,
including the resummation of threshold logarithms and Coulomb corrections
through next-to-next-to-leading logarithmic order, and top-antitop bound-state
contributions. The remaining theoretical and PDF uncertainties and prospects
for the measurement of the top mass from the total cross section are discussed.
