Every single video game system has been overtracked on VGCHARTZ, the wii nearly 250,000 units above what NPD shows. Playstation 2 about spot on, around 7,000 units overtracked, DS nearly 100,000 units overtracked, PSP over tracked by over 80,000 units, XBOX 360 overtracked by 50,000 units, Playstation 3 overtracked by nearly 120,000 units.
RE5 didnt boost hardware for either console, and killzone 2 didnt affect the PS3, it seems the economy is starting to affect video game sales in the U.S
