Neither year shows MS in front of the PS3. And only in 2011 and 2012 did it overtake the Wii in yearly totals. 2008 has 360 leading PS3... that is in fact the only full year the 360 has sold more than PS3 (2006 too, but that was PS3 launch year).
Neo Gaming-age forum (neogaf) claims vgchartz is not reliable and way off.
They call that site garbage, so I wouldn't trust anything from there.
You really need to check your sources (Just trying to help)
