Sony Computer Entertainment chairman Kazuo Hirai has slammed Microsoft's Xbox 360 console for not lasting long enough.

sony_logo Hirai told the Official PlayStation Magazine that Sony's consoles last for up to 10 years but that Microsoft's Xbox 360 has a lifespan of four to five years and "lacks longevity".

"Last time I checked, they've never had a console that's been on the market for more than four or five years and we've committed to a 10-year life cycle, so you do the math," he said.

And in response to claims by Microsoft last week that the Xbox is outselling Sony's Playstation 3 (PS3), Hirai is confident the PS3 will ultimately sell more consoles than the Xbox 360.

"Unless things go really bad, there's no way that at the end of a life cycle our competition is going to have a higher install base."

Hirai also revealed that Sony doesn't even consider the Nintendo Wii a real competitor to the PS3.

"It's difficult to talk about Nintendo because we don't look at their console as being competitors. They're a different world and we operate in our world - that's kind of the way I look at things."
