I think there will be a Playstation 5 ... but a Playstation 6 ... I doubt it.
By that time I think most people will get their games delivered to their TV/tablet via a streaming/network service.
Playstation Now is kind of the beginning, in 10-15 years that will be the norm.
Just like no one goes to Blockbuster Video anymore to get their movies, whereas just 10 years ago they were one of the biggest brands on the planet.
