Watch Dogs and Destiny both sold over 3 million copies on PS4 alone as of the 27th of September. Which directly means that a quarter of the installbase purchased these games.
Currently 6 games have sold more than 2 million copies on PS4 with a 7th, Killzone SF nearing that number as well with only 50k to go. That way it will get into the list with the other 2 million sellers: CoD, BF4, Fifa 14 and Fifa 15. Fifa 15 reached these numbers (2.20m) in just one week.
inFamous Second Son with 1.8m copies sold surpassed the previous game fairly easily in a very quick timeframe. Note that the game released in March this year and didn't need a lot of discounts or bundling that inFamous 2 did enjoy. It is on it's way to surpass the first installment too to become the best selling infamous game to date.
The Last of Us with nearly 1.5m keeps selling, in a faster pace than inFamous which is great for ND and Sony. With the high digital sales it is just a mather of time before Sony will announce a new 10m seller in their family.
