In an interview with Official PlayStation Magazine, the president discussed the place of the PlayStation brand in the industry.
"This is not meant in terms of numbers, or who's got the biggest install base, or who's selling most in any particular week or month, but I'd like to think that we continue official leadership in this industry," said Hirai.
Discussing the competition, he explained: "It's difficult to talk about Nintendo, because we don't look at their console as being a competitor. They're a different world, and we operate in our world - that's the kind of way I look at things.
"And with the Xbox - again, I can't come up with one word to fit. You need a word that describes something that lacks longevity."
When talking about developing for the console, Hirai says the initial learning curve pays off when the console has a ten-year life-span, and used PS2 adventure title God Of War as an example to show it had "a lot more to offer" late in that console's life.
