The PS4 has now passed the PS3 in total sales - per VGChartz estimates (thank you CGI!).
That now puts the PS4 in 4th place on the all time best selling home console list:
1 PS2 151+ million
2 PS1 104+ million
3 Wii 101+ million
4 PS4 87+ million
5 PS3 86+ million
The PS4 will easily fly past the Wii and PS1 by mid-next year - moving into the No. 2 spot behind the PS2.
Depending on when the PS5 is announced/released - the PS4 could challenge the PS2 for the no. 1 spot - especially when it hits that permanent $199 price drop- but will probably end up in the 120-130 million range when all is said and done.
