So we now know, thanks to Fallon, that KZ will be a PS4 launch title. Obviously we don't know the system price or if KZ will be bundled or anything, but let's take wild guesses anyway!
I say it'll be over 6m lifetime. I think it will be bundled with a "deluxe" SKU for the system ($499 with a bigger HDD also) and have the excellent MP and pretty graphics (obviously) to show what the PS4 can do. I think the social features will be used well as we know PS4 will come with a headset now. People will be posting their videos and there's nothing better for a game than to be the pretty exclusive FPS that launches with a system to show what it can do. I really think the series explodes as this is the first time it'll be at the forefront of a PS system's launch and advertising will be heavy as well.
For reference KZ2 did 2.88m so far and KZ3 is at 2.42m but KZ2 launched in 09 well into PS3's lifecycle. I don't believe either ever recieved a holiday bundle.
