2-4m i'd say. lots of variables to look at here.

I'm expecting Resistance: Fall Of Man numbers, so 3.5+ million units.

went with 3.5.

killzone has a small but dedicated fanbase that i believe will return. it will benefit slightly as a launch title much as resistance did when it got to about 4m.

lol op wtf are you smoking.

Killzone is a mediocre franchise. CG graphics didn't help killzone 2 and it certainly wont help Killzone SF. Being a launch title will give it some fresh appeal, the same way launch (and heavy bundling) helped Resistance. Do not expect more than 1.5M retail, 2.5 - 3 with bundles.

2.5-3.5 million depending in bundling and how well thesystem sell.

There are a lot if unknown factors here, specifically the game's local multiplayer support which I think will have w large impact. The success of the PS4 will also be very important. And we dont know about bundles, etc.

Since we don't know much about it, I say it'll do about similar to past Killzone games, so 2-3 million.

Probably going to be THE launch game of the system. So 4m id say.

Wow, I didn't know everything you said was fact.  We don't know how good this game will be from 6 minutes of footage.

Uncharted 2 just passed 6m so I don't think it's a completely bonkers number.  It is very bold I'll say, but I expect the social aspects to really pan out and everyone to get into the online now that it's out at the forefront of the system rather than coming after COD has already become the system's shooter.  Resistance sold 4m and that was a new IP.  KZ has a dedicated fanbase and the story isn't much to catch up on (seems like kind of a new storyline anyway) so newcomers will be welcome.  If it's bundled I can't see it going below 4m.
