Banks being hacked piss of people, pissed off people may or not may go to Bitcoin after that. I think its a minority until its more mainstream.
some of them will not decide to go with bitcoin or anything else, but simply they will put their money in their house in a safebox
so don't be so sure about the fact that the falling of the banks might help bitcoin's adoption, if they cannot trust banks they will not trust anyone with their money, i know their mentality, because it was mine too before knowing about bitcoin...
