Amazon is a bad place to use to determine sales trends because most people do not buy something online when they can walk into a store to buy it, and Amazon in the past has sold more items than it has confirmed (pending) inventory. Smaller games often do fairly well on Amazon because major retailers may not accept pre-orders on them, and systems regularly do better because most retailers only allow pre-orders on a portion of their expected shipments (sometimes as little as 50%) and this drives potential buyers to Amazon who has in the past sold far more than their expected shipment.

^^ So a few of you are saying Amazon sales dont matter because...its not...Gamestop?

It doesn't matter because it just ranks popularity in the last 24 hours / couple of days.

In other words, pretty much every single game ever created that's somewhat good will hold the number 1 spot on amazon for a day or two, people say "OH WOW number1 on amazon, this game is selling great!" And it never makes the NPD top 20 for the month.

I'm not sure whre you pulled gamestop from.

If PS3 slim wasn't #1, Sony would better be worried, because even with a remodel release they couldn't outsell the 360 or Wii.

I must clarify, I just looked up at the amazon top sellers, and it's updated hourly.

All the other PS3 models and software are already out of the top 10.

Currently it's

1. PS3 slim
2. Wii Sports Resort
3. Wii Motion plus
4. Wii remote
5. xbox live card
6.Nunchuk
7. Wii
8. peggle
9. madden 360
10 madden PS3.

that is why we do not use Amazon as a sales indicator.

As you may know, the PlayStation 3 120 GB is in great demand, and there are shortages of this product across the U.S. and our stock is faltering, In an effort to provide as many customers as possible with the opportunity to purchase PlayStation 3 120 GB, we are limiting the total number of PlayStation 3 120 GB units that can be purchased. As a result, each household may only purchase one PlayStation 3 120 GB unit. See additional policy details here. We apologize for any inconvenience.

^^ QUOTE FROM AMAZON.

good day, good sir.

and?

How can their stock be running out when they don't have any yet.

1.) It's Called Preorders there buddy, stores dont have unlimited pre-order numbers.

2.) They DO have it in stock, most stores have had it in stock for the past 2 weeks, Kmart, the place that half the leaks came from for one.

Good, now whats your point. that the Ps3 Slim will have good launch numbers? Obviously, it's a remodel, i'm not arguing the PS3 slim will fail and have a terrible launch.

Now about Amazon being a reliable sales source...I hope you still do not believe this.

For its own sales...Its quite reliable, its not like its predicting the overall sales of every Website lol.

.......

For it's own sales its not just reliable, it's dead on. How can a list of the actual sales figure for your own website be wrong?.It's like saying "Hmm, i've sold 5 glasses of lemonade, i think that figure is pretty reliable of my actual lemonade sales"

The point is not that Amazon list is wrong for what Amazon sells, it's exatly right. The point is that you can't use it to determine the success of something as it is just anecdotal evidence.

I should add that the top sellers list, although accurate,  is still only the best sellers of the past few days or so.
