I can't believe that there's any possibility of banks doing anything of value on the Bitcoin blockchain when they could easily coopt the blockchain tech and set up trusted miners. The public immutable ledger with full transaction history is obviously interesting to Wall St. but what are the chances any of these banks will trust anything of value to the current ideological devs of a ~$3B commodity controlled entirely by unknown Chinese miners? The underlying notional of anything interesting on Wall St. is measured in trillions.. Can you imagine them suffering through the squabbling with the block size debate or hoping that miners don't collude to roll back the last month's transactions?
