The PS3 total sales have recently surpassed the Wii in Americas sales... I made a thread back in 2008 when the last change took place... that was Wii Americas sales overtaking the PS3 overall sales: http://www.vgchartz.com/forum/thread.php?id=52564
Now the PS3 has brought it back to parity and in the past 2 weeks has taken the lead again.
PS3 overall stands at:
168,586 (-2%) | 31,821,914 |
Compared to the Wii in Americas:
151,331 (-11%) | 31,804,909 |
The Wii has been ahead for quite a while as can be seen in this graph:
but the PS3 slim has given the PS3 enough momentum to catch up.
