I guess this is why we got Heavy Rain. Sony in this case did support the talent to create a new IP. Sony took a risk on Heavy Rain and it paid off, some you win some you lose. Just to add this game could have been an MS exclusive.
David Cage, says that the only reason it was able to become a "commercial success" was because Sony had enough "balls" to take a risk on the Quantic Dream developed product.
"Publishers in general don't have balls," he said. "That's a fact. They want a safe bet. They look at what was successful last year, and ask you to do the same. You need to give them reasons to trust you... With a game like Heavy Rain, it comes together very late. If I showed you the alpha of Heavy Rain, you'd probably kill it and say that it would never happen. Many publishers would have killed that game at that stage. Sony didn't."
"Very few developers take risks, or have opportunities to do so. But the market is ready for that ... now I can say that for sure. Heavy Rain is a commercial success, which is something that nobody at Sony or [Quantic Dream] expected, to be honest with you."

Quantic Dream's Guillaume de Fondaumiere revealed to a Digital Dragons audience in Poland today that PlayStation 3 exclusive Heavy Rain cost just €16.7 million to make
With Sony's marketing and distribution on top, the total spend looked something like €40 million. But, Fondaumiere said, "Sony earned more than €100 million with this game. It's very profitable."
