I think the Sixth Generation doesn't end yet, since the PS2 still in production?
I was going to wait for the Sixth gen to talk about that, but if you like I can say it here. I know this will be controversial, but I have two problems with the notion that the PS2s lifespan continues on because it's still in production:
1) PS2 sales started dropping as soon as the PS3 was released, that's why they took PS2 BC out of the PS3. For that reason, the PS2s lifespan has been artificially extended, as now it only sells Guitar Hero games and PSP ports.
2) The Famicom stopped production in 2003, but no one questioned the end of it's lifespan was in '92 (some might also note that the second version of the NES was released then, and many games were released afterward). The Dreamcast, as we'll see, still has games being released for it, but no one will question that its life ended in the early 2000s. Even the PS1, will anyone here say that the PS1 really survived till 2006? 6 years after the PS2 was released? Really?
Basically, when Sony says they have a '10 year lifecycle' for their consoles, they're referring to how long they plan on making the system. As soon as a new console is released EVERYONE, developers and consumers, flock to the new console.
Sony wants to make money and the PS2 is cheap to make now and people do buy it, I completely understand that. But limping along, leeching off of the PSPs library does not constitute a life, imho. Frankly, I felt I was being generous by saying it ended in 2011, just like I was in saying the fifth gen ended in '06.
