They're not really there yet, though; right now it seems like Tesla's still raising capital via the Model S and (eventually) the Model X. A significantly-cheaper Tesla (which probably ain't the Model X) will probably arrive alongside the new battery-churning Gigafactory they're building here in Reno (since that'll allow for better economies of scale with the batteries at least), which is slated for completion by around 2017 IIRC.
