A few things that concern me:
Bernanke says that QE is not inflationary, but that he is worried about deflation and won't let it happen....if QE is not inflationary then how can it fight deflation?
I don't believe QE is inflationary, its an asset swap (as Bernanke states). This doesn't mean that others won't believe it is inflationary and push up asset prices as a speculation.
I think the worst quote is when the interviewer asks whether he is able to control things and he said he was "100% confident". Famous last words.
He says the goal is to lower rates, yet doesn't talk about liquidity traps or that QE has not worked in Japan.
