PS3 to last 15 years?

[GiggityNinja]

I could see 10 years... but the system starting to lose its luster by its 8th year, making sales decline. By the 10th it will have still survived, but will have sold barely anything (compared to its competition). Of course, Hirai planned 10 years, so it makes sense.
As for 15 years, I will only say, using my above statement as some sort of thesis, that it is possible. Not probable or likely at all, but possible.
