I suspect that like most of the previous observations of faster than light effects some unaccounted for factor will be found that reduces the measured speed. The fact that neutrinos in the wild don't seem to do this is a large "wait and see" flag to me.

...almost exactly what the OPERA team observed.


In a circumstance that revolves around precision of measurement, it seems odd that phrases such as "almost exactly" are used.

It's hard to say from a news article. Who knows the context of the quoted material?

I read "almost exactly" to be what a physicist says when s/he's speaking to a lay audience about something that's exact from a lay POV but can't quite bring hirself to say it without a qualifier.
