You are looking at the completely wrong stock levels on Amazon. That is people reselling stuff, not Amazon stock.

So 4 months into launch people are already preach doom and gloom. Much like a rerun of ps3 vs x360 but the same people would be arguing on behalf of sony 8 years ago, and they wouldn't be wrong because tables have turned late in the gen. There are still plenty of years left in the gem, and contrary to popular belief they are essentially the same consoles that will receive exactly the same third party support, and that's what sets them apart this and last gen from wii/wiiu

It was definitely limited in America also until very recently. We just got new shipments this month, it still is very supply constrained.

First off, I am talking about the bigger picture and what I believe is the road this generation took even before it began.

Second, I am looking at the best sellers list where there are 414 used&new PS4´s and 20 new X1 titanfall bundles. What am I doing wrong there?

XB1 won't fall to WiiU levels.

Also this. It's pretty silly that people are still saying Xbox One will do as bad as Wii U (some still think it will do worse).

The PS4 is tracking ahead of the Wii. It defined all the launch records, even the PS camera sold 1M. How are they on its way out? MS and Nintendo are the ones that have to be worried. If PS4 current numbers aren't good, then we could call the Wii and the PS2 launch flops.

You are saying they are not constrained because of these numbers (414 & 20) but they are the wrong numbers to use for this claim. That is what other people are selling on Amazon, not Amazon themselves, so there will always be units for sale. Both consoles have 1000+ units from Amazon direct at the moment. 

Because that stock is only about a week old and there's already only 400 left. That's a pretty big stock issue.

Edit: I didn't see that it was "offers". If you look at the offeres, only one is being sold at msrp.

Amazon themselves have more than 1000 units.
