Killzone 2 is currently in second place in the Amazon video game best sellers list behind only Wii Fit.  This is especially impressive since the game isn't out for another month.  This is very anecdotal data but hopefully its an indicator of how overall pre-sales are going.

Don't flame me if its not #2 when you check, these rankings are updated hourly!

my baby seal!!!!

cool.

in case your wondering about the seal picture above, it is because it has been proven over and over again that where a game ranks on Amazon.com means absolutely nothing.

so anyways, every time you quot amazon.com sales someone clubs a seal. Think of the seals.

Probably because of the coupon code for $5 discount.

haha, my bad. I had no idea. As you can see from my post count, I'm new to the boards.

It doesn't hurt that its ranked that high. Games that have had huge openings recently like Fable 2, Gears 2, CoD, World of Warcraft, etc. have all been in the Amazon top 5 as its launch approached. So while its obviously not 100% reliable, there is definitely some correlation.

Just to give you an idea of how bad Amazon rankings can be, GTAIV was not the #1 title on Amazon in its launch week.

Wasn't WoW: Wrath of the Lich King number one for about a month on amazon and it sold 2.8 million in the first 24 hours of its release?

Don't worry, KZ2 will sell fine, but not because it's #1 at Amazon ;)
