Either this is a very biased article, or the interviewed physicists are being extremely polite. The odds of finding new phenomena aren't bad, happens all the time in physics, but of overturning Einsteinian physics? Not very likely, in my opinion.
CERN's reputation for quality research is well deserved, so it wouldn't surprise me at all if the results were replicated, but I'm expecting an eventual explanation consistent with Einstein. This has the same feel as that discovery a decade or so ago of light packets that could arrive before they departed.
Also, given that Fermilab is scheduled to discontinue operation at the end of this year, they might not have sufficient time to do the necessary setup work to their neutrino facility, and experimenters currently on the schedule through the year's end will fight hard to maintain their place.

Re: Let's Speculate

The expected arrival time calculations are made based on the mean time value of the departure pulse, when infact (if this speculation is correct) the only neutrinos detected were at the leading edge of that pulse (slightly) prior to the mean time value given for the departure. Nothing superluminal here.

Physics Saved!
Geez, the explanation is even more mundane than we guessed, different reference frames. Found several articles:
This proposed solution has yet to be vetted, but I bet it sticks. Faster than light particles, physics overturned, physicists baffled, science in an uproar: sheesh!

Read This Article
Sometimes one comes across a piece of writing so exceptional it almost makes one weep. I came to this article via Google News and didn't pay any attention to the source or the author. I clicked because I was interested in checking in on the latest news about the CERN neutrino experiment, so I began reading, fully expecting that within a minute or two I'd be on to the next Google News article.
After a couple minutes I looked at the scroll bar and saw I was only a third of the way through the article. "Who is hosting such a long article?" I asked myself. Glancing at the top the page I saw it was Scientific American. Of course, who else?
So I fetched a fresh cup of coffee and a snack and sat down to enjoy the rest of the article. About 2/3 of the way through I was so boggled by the clarity and quality that I had to know who wrote it. Turns out it was Tom Levenson, Professor of Scientific Writing at MIT.
Those of you who feel like you haven't really understood the science will almost be convinced that you do. Those of you who believe you do understand the science (and at least a few of us are right) will receive the benefit of examples of explanations that seem like gifts from God.

It appears that Tom Levenson is yet another person who has (provisionally, to his credit) boarded the bandwagon proclaiming that Ronald A.J. van Elburg has offered the correct explanation of the observed neutrino time-of-flight discrepancy via special relativity.
Hmmm - I didn't reach the same conclusion that he'd jumped onto that bandwagon:
It’s not as open and shut as all that. Elburg’s argument makes the assumption that the OPERA team failed to account for the quite well-known special relativistic effects on GPS signals and while they may have, we don’t know that yet. At the same time the original OPERA paper reports some checks on the timekeeping essential to the experiment. I understand that the group is working through the long list of necessary responses to specific suggestions like this one while at the same time preparing for a yet higher precision measurement of the effect they think they have seen.
But even if he had gone all wild-eyed and giddy over the Elburg argument it wouldn't change how outstanding an article it is. From general descriptions about the nature of science to specific applications of science to areas like global warming, I just found it exceptionally exceptional.

Darn, it would have been so fun to blow people's mind.
If the supraluminal transmission results prove out it will be absolutely mind-blowing to science and probably initiate a period of both new theory and new discovery. I personally don't believe they'll prove out, but if they did, wow!
This love of new discovery is what creationists think is absent in science. They see science as paranoidly defending the status quo when all we're really doing is following the evidence trail. We would love it if actual scientific evidence were uncovered of a young earth or a designer. It isn't these ideas in themselves that we decry but the lack of evidence.

"Speed of light" experiment professor resigns
From Page Not Found | Reuters:
(Reuters) - The Italian professor who led an experiment which initially appeared to challenge one of the fundaments of modern physics by showing particles moving faster than the speed of light, has resigned after the finding was overturned earlier this month.
Seems a bit of an overreaction. Mistakes are part of science.
