Heavy Rain Trophy delay

It was announced that Heavy Rain will delay their trophy unlocked ding. It will ding after the chapter is completed and not during cutscenes. They needed to get Sony's consent to do this. I wonder why. Anyway, I like the idea because one too many times I have been distracted by the ding when I view the cutscene. Considering how many secret trophies there are (52), you can guess that many are chapter-related. The game comes out in late February.
