@Jesse2050, All it has to do is maintain its current sales rate (of a bit under 30 million) and it can easily hit 140 million. Also, I can see the hardware to continue to sale for a little bit into the lifespan of the next DS because it would be a cheaper alternative. Also, since sales of the DS have alreadly surpassed the PS2 in Japan, I see potential for the DS to surpass the PS2 in total worldwide sales meaning over 120 million.
In the end, I suspect between 110 and 140 million units total worldwide.
