I certainly hope the PS3 isn't Sony's primary console after another 3 years. I seriously doubt Nintendo and MS are going to wait a total of 10 years to release new consoles, and I can't buy the hype that the PS3 could still be "leading edge" performance-wise if that happens. Processor/bus/memory/etc advances just don't crawl along that slowly.
For those who say, "Sony wants to keep the PS3 around for 10 years", that doesn't really determine much from a product standpoint. I would love it if my home computer could play the latest games after 10 years, but the only way to come even close to making that happen is to basically replace all the internals with much more advanced components... motherboard, drives, memory, etc. You can't do that with a PS3 and still call it a PS3.
And before someone points out that the PS3 Slim has a "new" motherboard, etc., you need to think about the fact that the changes to the processor, graphics, etc. are slightly upgraded--primarily with power-savings in mind, not redesigns of those components.
