Barack Obama signals that he will cave over missile defence and the BBC just yawn

At a meeting with current Russian President Medvedev at a nuclear summit in Seoul, Barack Obama let slip when he thought the microphones were off that:
"This is my last election. After my election I have more flexibility"
President Medvedev then said that he would relay the US president's position to president-elect Vladimir Putin.

To the BBC this is a piece of minor news, I have yet to hear it reported on the radio and the BBC news website has just this little piece

If the US President revealing that he will likely cave into Russian pressure on missile defence once the inconvenience of a Presidential election was safely passed, is not news then what is?
