If Sony really tries to do the PS3 / PSV strategy again with the PS4, they will be in serious trouble. The PS3 basically lost 1 billion USD / year since release and the Vita seems like it is losing money as well.
It is about time Sony stops listening to their internet fanboys and make hardware that is powerful and affordable. A console 6 times as powerful as the PS3 is more than enough if you look at Uncharted or Killzone graphics.
Imagine not having GamePass on your console...
