  Updated predictions are presented for high energy neutrino and antineutrino
charged and neutral current cross-sections within the conventional DGLAP
formalism of NLO QCD using modern PDF fits. PDF uncertainties from model
assumptions and parametrization bias are considered in addition to the
experimental uncertainties. Particular attention is paid to assumptions and
biases which could signal the need for extension of the conventional formalism
to include effects such as ln(1/x) resummation or non-linear effects of high
gluon density.
