I think not.
This is really a typical article published because the Americans at FermiLab want to show that they're still "alive" under the growing shadow of the European LHC.
So from time to time they publish these "great findings".
Once the LHC is in full operation they will become pretty obsolete, roughly put.
Eventually they will build an even bigger/more sophisticated collider in the USA and then the Europeans will do so, and on and on...
The competition in science is greater than one might expect.
I interpret these kind of low-news articles as a "proof of life" for Fermilab.
