I have always believed that PS4 exclusives target a more mature audience and that's what I like about them.
A good example, is the "Heavy Rain story behind the story". There is an interview out there in which David Cage is asked about the PS3 exclusivity. He explains that he actually asked Microsoft to fund the project before asking Sony.
He assures that the response Microsoft gave him was negative and that they wanted him to change the plot, because the script that he gave them was "too dark", the link for the article is below:

To wrap up, I will not change PlayStation exclusives for anything, even if the console was weaker.
