Well I think this site charts are more adjusted to reality that the 4.28 number ,and especially that the 4.48 one .
I would give the PS3 some 4 million sold .
Still ,what I am saying is that this time Sony has explicitly said it wasnt speaking about shipped numbers but about sold to customers .Thats why I added the other link .
For anyone who reads that it is legit to think this site numbers are slighty off ,its not that he is a irrational hater or anything .I personally think it has some 4 million ,so I am closer to vgchartz numbers that to Sony numbers ,but I dont see as a MANIAC and a Hater someone who reading that SOny claims 4.28 million sold to customers emphazising it is not shipped but sold to customers actually thinks it must have 4.28 million sold .After all Sony has direct access to all the data from NPD ,Media Create ,Gamecharts ,GFK etc ...
