It is the inevitable future! Banks will eventually have to move to the digital currencies whether they like it or not! However, please note the point that, these digital currencies will simple be a digital representation of the paper money and nothing else! So there's nothing to get excited about! Mark my word, that Banks will never support a semi-anonymous digital currency or decentralization, no country would approve this move. It's simply a number in your bank account instead of holding cold hard cash! Centralized and strictly controlled by the governments!
I agree that it will be the same digital currency as now Fiat money, only the question remains how many will be issued.
This is so only about the countries who are dependent on the IMF and not about those who are not prone to regulations by the IMF. However it also depends on the degree to which a country depends on IMF. Anyhow, it might prove good for the economies that are struggling like Venezuela.
