Considering the largest PS4 userbase is at the moment in the US, where the game wasn't bundled, and that the bundle was introduced in Scandinavia less than a month before the launch (changing your existing pre-order to the bundle would have meant a loss of your place in the line), I'd say its actual sales were quite high.

Fair enough, but that data is nearly 7 weeks old. And dont forget that Killzone was part in some major promotions (Buy 3 get one for free). Its still an impressive result but it doesnt really disable what I said.
Ps: Apperantly more german sites posted this news.
