With the PlayStation 4 just 24 hours away from launching in the U.S. market, Sony is expecting big sales of the next-generation console.

The company intends to sell three million units by the end of 2013, according to estimates by Jack Tretton, president and chief executive officer of Sony’s U.S. computer entertainment division.

“This is a marathon, not a sprint, but getting out to a nice start is a good thing,” said Tretton. “That hurdle has been cleared. We’re very, very confident we’re in great shape.”

The system is also expected to be in greater supply than the PlayStation 3 was back in 2006. “We’re very comfortable with it,” Tretton said regarding the estimate. “I’m excited about next week to be able to talk about what was sold as opposed to what we may sell.”
