Tesla's Musk says capacitors "will supercede" batteries

While speaking at the Cleantech Forum in San Francisco, CA last week, Elon Musk, chief executive officer of Tesla, said he's willing to bet against batteries to be the technology that finally delivers the breakthrough that electric-drive vehicles need to become mainstream. Earth2Tech quotes Musk saying:
If I were to make a prediction, I'd think there's a good chance that it is not batteries. But capacitors.
Tesla's electric vehicles utilize lithium-ion batteries, which makes Musk's comment unexpected. But, Earth2Tech says, maybe Tesla is researching capacitors in its Palo Alto, CA. labs and points out that Musk originally came to California many moons ago to research advanced capacitors at Stanford University. While Musk says that he attended Stanford "for a laugh," he also claims that at some point, capacitors "will supercede" batteries. Who's going to be laughing when that happens?
