If I am not mistaken, In the states the FDIC Chair said they were looking to see how or what roles a bank can play in the industry. At the end of the day, it is about profit for banks and maintaining that stream of income as a business, even if a bank. As Jurassic Park chaotician said,"Life Finds a way".
I can agree with that quote, I think that banks will try to fit in no matter what because they want to survive and these bankers know how urgent it is to be able to survive when they're very existence is threatened, I mean that's what any sane business person would do right? Find ways to keep your money maker alive. The claim on the title though, I don't think that it's going to be a happening in that timeframe, as long as capitalist and greedy bankers rule the world, banks will stay alive.
