PS3 peaked way in 2011 because the PS3 didn't start doing good until 2009. PS4 won't live as long. The PS4 won't reach 25 million. Even the PS2... the best selling console of all time... peaked at 22 million I believe. PS4 will probably peak around 20 million IMO. Maybe not even that. It will have sony legs.. not the high peak and sharp drop of the Wii.
