Tevatron discovers CP violation in B meson decays

Apparantly a paper was just submitted for review about the finding of another CP violation. Link for reference.

They seem to think that this one might not be as infrequent as the others, and may better explain the prevalence of matter in the universe over anitmatter.

I'm a little surprised that they don't reference the previous Tevatron measurement: Phys.Rev.D55:2546-2558 (1997). The new value is not just inconsistent with the standard model, but it's inconsistent with the previous measurement as well.
