Fermilab KTeV-E832 recently announced their final result, Re(epsilon'/epsilon) = [19.2 +- 2.1] x 10^{-4}. The new world average shows the existence of direct CP violation in the decay process itself with 12 standard deviations.3 pages, 6 figures, Flavor Physics & CP Violation Conference, Taipei, 2008High Energy Physics - Experimenttext
