Yesterday we learned that Nintendo is in no hurry to create a Wii successor. Today, Sony said something quite similar. In an interview with Fast Company, SCEA America CEO Jack Tretton says his company has just scratched the surface with the PS3.

The chief executive went on to tell the business magazine that the PS3 has only lived 25% to 30% of its life cycle. Considering that the console launched in 2006, Tretton believes the PS3 will be around for a very long time.

In the old days, it was, "This thing is dead as a door nail in 5 years." Year one is very important, year three you're already starting to get to the other side of the hill and then there's a slippery slope. We've just passed the third year of the PlayStation 3 and we're just hitting our stride. And I don't think anyone is saying, "This is a five-year cycle; what's new on the horizon?" I can't even imagine what can be done technically beyond the PlayStation 3 in the near future. A question I often get is when we are going to see PlayStation 4. When somebody can craft the technology that exceeds what we're able to do on the PS3, but we are still just starting to harness it.

Sharkey says: With Blu-ray, the PS3 definitely has the greater potential staying power. And it appears both Sony and Microsoft believe their motion controllers will rejuvenate this generation of consoles. How many birthdays do you think the PS3 will celebrate before its console heir is born?
