Ezra Klein's hunch:
[W]e're eventually going to have to face up to the elephant in the room: prices. We can't keep paying twice as much as other countries pay for each unit of care and get our costs under control. I think there's virtually no chance that this system evolves toward single-payer. But I think there's some chance that the government eventually begins setting payment rates for private payers, much as happens (successfully!) in Maryland.
