No, PS3 will not be here 10 years. The only consoles in a generation that has a chance of being around for more than 6 years is the generational leaders. This because that console already has the greater majority of support and can keep pushing out quality games even after the next gen starts. Why do you think the PS2 sales have rivaled 360/PS3 sales throughout this year? So long as Wii remains in a comfortable lead, it is the only machine with any possibility of lasting 10 years.
Now, based on Nintendo's plan thus far, it won't as I see Nintendo bringing out WiiHD within 6 years at about the same time PS4 and Xbox3 makes a debut. Of course, the latter two's strategies will have changed dramatically.
