Killzone 2 was the best selling one with around 3 million or something right?
Hmm....hard to say. On the one hand, Killzone has never really quite taken off as a huge shooter, but with a new generation starting this is as good a chance as it's going to get, and it does have the added benefit of being the only big exclusive PS4 has for launch. It could very well end up being the best selling title in the franchise.
I'll be conservative and say 3.5 million. It could do more if it really takes off, or if Sony decide to mass bundle it at some point, but otherwise I don't know if it will vastly outshine it's predecessors
