You guys have the wrong context...
FF13 original sold something like 7 mil life time.
So if FF15 is a better game than 13 (considering 13 is not universally acclaimed), selling 3 mil more is not that hard.
Not to mention the DLC market is like 2-3 times bigger than when 13 was released. That's some more money right there.
