Or the light is slightly subluminal and the nevtrinos are (almost) luminal at their speed.
May be a bunch of reasons, more probable than the assumed one.
What do you mean by that light is subluminal? Literally it means that light travels slower than light, which is probably not the intended meaning.

Perhaps the end of the era of the light cone and beginning of the era of the neutrino cone? I'd be curious to see your probability estimates for whether this theory pans out. Or other crackpot hypotheses to explain the results.
