Sony has indicated its priority with PlayStation 4 is to have it be the "best" next generation console, not being cheapest or beating Microsoft's next Xbox to market.
Speaking on Gametrailers, Sony Computer Entertainment US boss Jack Tretton said it is better to build a better machine and have it launch after its rivals than rushing it out.
"We've never been first. We've never been cheapest. It's about being the best," he said.
"If you can build a better machine and it's going to come out a little bit later, that's better than rushing something to market that's going to run out of gas for the long term.
"Ideally, in a perfect world, you want the best machine that ships first that's cheapest. But the number one goal is to be the best machine and that's what we're always focused on."
