I wonder why people keep insisting in technological upperhand and sales numbers, one of main aspects that cemented 360's rep was the release of both Gears and Halo 3 which created enough hype to make the xbox gain some attention, PS3 back at those days had nothing just MGS4(and that was 2007).
I'm not really sure about the 10 years lifetime plans, considering technology advances(specially in the computing areas) is quite hard to make that plan work. Apart from that, there are not only technology changes but also the distribution methods(DLC, physical media formats and such) and future platform that might take off depending on different technologies that might be develop by the time(personally I find physical media very outdated for a new console, having more than one drive is actually quite redundant, not to mention that digital distribution slightly help to control piracy).
And then there is also the whole "game" aspects of these games consoles, I think that they should focus on making a developer friendly platform while being capable of outputting enough power to renders and complex engines, SDKs are also something that I expect to see more in future game consoles(Playstation Suite seems quite promising, by watching some tech demos you can tell that is actually quite easy and flexible(it uses C sharp like any other PS console but it actually seems easier to test and compile). I think that use wants to see what happens first with the Vita, they making pretty big things with that thing, things that are only being scratch on the very surface to this day(granted they are competing with IOS and working on Mobile environment platforms, however the potential from such platforms applied to home consoles is quite high).
