I sadly don't believe that the banking system will ever adopt bitcoin, If they start doing so, It would be for a particular reason they hide (most likely to eventually control bitcoin). The maximum that could happen right now is making bitcoin legal in some countries.
Agreed. There is a direct conflict of interest for the central bankers to start accepting bitcoin in their business model. Have you heard that bitcoin traders were basically denied bank accounts in australia a few years ago, and existing bank accounts were frozen? If not for the laws in place, then that would have been the end of bitcoin trading in that country. As people said, the main point here is that they're not even saying that it's going to be bitcoin. It may be any altcoin, developed by whoever. Might even be the bank themselves.
