I'm much more cynical. I suspect Biden will have a ‘non-fatal’ heart attack. Hillary! will then be asked to step in. I'm not yet clear as to whether she will actually accept the invitation. She's too good a politician to intentionally go with a sinking ship.

They don’t have time and the ballots are either printed or in the process of being printed — some states shortly will start early/absentee voting. They would have to go to court in all states and there is not enough time.

Switch is not going to happen plus Hillary would not take a chance of the ticket losing with her on it — she is now looking to 2012 and forget about Obama.
