Its interesting … neutrinos oscillate from one flavour to another (this was observed last year in May). This means they have a small, but non-zero mass. The MINOS experiment then measured oscillation differences between mass eigenstates, (2 and 3, according to Wiki), which means that there is at least one neutrino with a mass of at least 0.04eV.
That's pretty tiny !
One has to wonder about the uncertainty/error bars of the newly measured velocity. I guess all we can do is wait and let other 'pros' review the analysis and replicate the results. (Which is what the CERN team are requesting … a normal part of the process .. and the media will hype this up beyond belief, I'm sure of that !)
Cheers
