You are an idiot (like most others here), I will soon stop wasting my time. Talking to brick walls in the thread here. Sony is a publicly listed company and report R&D costs for their gaming business, which has been more than $1Bn per year for the past 10 years. Most of this is relating to hardware. The typical hardware console cycle is 5-6 years. They start development on the new one right after they have finished the past one. So to look at the total investment for a hardware cycle you easily get into multi-billions just on R&D.
