PS2 shipped 117 million consoles until March 31 2007 according to official numbers by Sony, so basically sold 40 million more alongside PS3. Obviously PS3 is not PS2, but doesn't need to be. If Wii stops selling and ends with 101-102 million lifetime and PS3 finish 2013 around 82-83 million, it needs 20 million more or less to beat Wii. I think Ps3 will last until end 2018, that's an average of 4 million each year.
It will be close and difficult but PS3 CAN overtake Wii.
