PS4 to last 10 years or more according to Sony

Gamerspective – It seems that Sony want the PS4 to have a very long generation with the PS4, in fact 10 years or more. Which although some disliek the idea of a long generation, the idea that the PS4 could be still used for the next 10 years makes it feel that Sony are taking this seriously. However, the PS2 was launched in 2000 and wasn't discontinued for almost 13 years.
