It looks like there'll be further models after the Three:
"I'm super excited about being able to produce a car that most people can afford," Musk said. "And there will be future cars that are even more affordable down the road."
"With something like the Model 3, it's designed such that roughly half the people can afford the car," he continued. "With fourth generation and smaller cars and what not, we'll ultimately be in the position where almost everyone will be able to afford the car."
