Percentages mean nothing.You have to look at the actual numbers.
As others have stated,GT4 sold over 9 million,I guess that means it flopped because not even 10% of owners bought it.
The fact is it sold 9 million.9 million is awesome.
Killzone 2 has sold 1.32 million in it's 5th week. That's really good,despite it's percentage to total user-base.
