Well, the fact that CP violation is related to the "existence of the universe" (which I guess refers to Baryogenesis) is not ambitious. It's also not terribly surprising that there would be CP violation in neutrinos. It's true that the significance isn't enough to meet the standard in particle physics, but a result will always be weak before it is strong, so this is still something that's exciting. It should also be noted that the 5-sigma "standard" is set to be so stringent partially because physicists in the past were not so good at estimating things like trial factors and systematic errors. We are better at this now (and T2K has some talented statistics-minded physicists on it), so I wouldn't immediately dismiss it on those grounds.
