If my information is correct, PS2's SW was at 1,537 Billion at march 2012. The last games came out late 2013 (FIFA 14, PES14) and thats it. I highly doubt many more games where sold past this point so its clearly below 1,6 billion. If Nintendo really does not include games without a physical version (1st, 2nd and 3rd party) then the actual number is a damn lot higher than 1,359,90 Billion!
