This is probably a stupid question... I'm wondering if, to use these features,a person will have to buy the game for the ps vita and the ps4. Can the vita be used as a controller for a game playing on the ps4 without also have the game for the vita? Can a vita be playing a game and stream the image and sound to the tv screen throught the ps4 without also having the game on the ps4. I'm basically asking if the game makers will be double dipping from the consumer to be able to use the features? Will somebody please clear this up and elaborate on this for me?
