The same people that are out declaring extreme low prices are one who were also saying we were going to hit $200, $300, even $500 oil just a few months ago...
Most of the ones who are making all the proclamations do so because it gets them more interviews from a media industry that thrives on the sensational.
Prices dont' just arbitrarily move up or down. Oil prices "bubbled" because they were being driven to do so by the speculators who were taking advantage of the control they had at the time. The crude prices would have not gotten that high that fast left to normal market conditions.
Likewise, crude prices don't just fall due to gravity, and most especially not just because some talking head on the TV says they will. The forces that can influence the market prices most likely won't let it. It's kind of like proving a murder in court... there usually has to be a motive and suitable circumstances before claims can be believed.
