From the same article:

But the excitement in the physics community is tempered with a loud note of caution. Although the Fermilab result is the most accurate measurement of the mass of the W boson to date, it is at odds with two of the next most accurate measurements from two separate experiments which are in line with the Standard Model.

So... 2 experiments + theory Vs 1 'better' experiment.

I know which side I'd bet on.
