I cant see it. Currently looking at the specs of these consoles this generation is not going to last long. Even 8-9 years of the last generation was severly a mistake. I expect we will see new consoles by 2018 so unless ps4 sells amazinglyi do t see it

There will be no need for a new gen quickly, what ever the jump in specs it will have a marginal effect on the games.  

Snes to PS to PS2 to PS3, such massive leaps are a thing of the past now.
