This Killzone will be the PS4's best selling first party FPS. Which isn't saying much. Because it's a launch title. And PS3's best selling FPS was also a launch title. With only 4 million sales. Killzone is not even one in the same Super Mario Galaxy as COD or Battlefield. Even calling it a distant 3rd is too much credit because that assumes that there was other competition lol. It will sell well-ish because there's no other 1st party launch competition.

Though I wish this would happen it wont, I dont even think it will outsellf BF or COD just on the ps4 alone.

It will never happen, call of duty and battlefield will outsell it and they could even outsell it on PS4

My source is common sense and history.

are you sure you are listening to it? because really, why would CoD be the most pre-orded SKU when GTA is about to come out? why would it be the most pre-orderd SKU when Activision them selfs said pre-orders are low? your sources seem pretty off, at least give us sources that are credible 

What? I'm not comparing to GTA I'm talking about which COD sku is ahead and how that is different to the pre order numbers shown here.

i guess you were talking about the pre-orders of FPS's alone then? i thought you were talking about all pre-order charts

I was talking about COD and nothing else.

then i agree. 360 SKU will be, by far, the more pre-orderd one

Yeah not even close.
