I'd be lying if I didn't say I expected this, but another laboratory, lead by M. Antonello, has published a paper, not yet peer reviewed, which claims to refute the idea that the OPERA neutrinos are travelling at super-luminal velocities and suggests they are instead "merely" travelling at the speed of light. The study is based on an idea analogous to Cerenkov Radiation, where a superluminal particle should throw off lower-energy photons as it moves... an idea that has also not been peer-reviewed or demonstrated. The Cerenkov-Analogue was presented in a paper by Andrew Cohen and Sheldon Glasgow.
The papers are provided above in Portable Document Format, once again courtesy of Arxiv. The language is very technical and I'm not done with reading any paper yet. I hope to have them finished by the end of the night so that I can comment more effectively.
