Considering 21 million Uncharted sales (all combined), 85.9 million ps3 sales (vgchartz) = 75% never played an Uncharted game. 50% of ps4 owners didn't own a ps3, 25.4 / 2 = 12.7 million plus 75% of the other half is a total of 22.2 million potential ps4 customers that never played Uncharted or 87% of the current ps4 install base.
I can do math too.
