Bold #1: I don't think you understand how capitalism works. It's pretty self correcting. Even if a bunch of scalpers started hoarding the product and making them scarce in stores, when people go on eBay for example and see 10,000 PS4s on there, they're not gonna bid one up a whole bunch because there's other listings. If they can't find one in stores and on top of that, only 200 units are on ebay, then they'll bid them up because there's way less supply (and that people actually aren't scalping the product since there aren't a whole bunch being listed).

Bold #2 and yet it sells out pretty much immediately whenever stock is available. A product constantly selling out as soon as its available not indicating a "market rush to get the item" can only exist in Bizarro world.

You need to understand that demand can decline and still be very high. So, when someone says PS4 demand seems to be decreasing, that doesn't mean that the supply has cught up with the demand or that no one wnats a PS4 anymore. It just means that the number of people ready to buy the console right now at inflated cost is going down. This will reflect in the price in the second hand market (or the equilibrium price is going down if you will). Unless the PS4 doesn't follow the normal laws of supply and demand (hint: it does) a decreasing price in the secondhand market means either that supply is going up or demand is going down.

So, in your example of 10 000 scalpers. If they can't get the price they are looking for, that is because the demand is not strong enough to support the price with the given supply. Also, not sure why you frame that concept as capitalism as it's really just a fundamental function of a market economy. Of course, a free market is a central concept in capitalism but it's not like supply and demand doesn't affect the price in other types of economic systems as well.

And the 7th gen pretty much broke all historical precedent. There's never been as fragmented a video gaming market than the one we're getting into now.

When you take out Wii's Blue Ocean (probably 50% of Wii's sales), which was largely a one generation wonder as evidenced by Wii U's dismal Gamecube-like sales, the 7th gen looks a lot like the 6th gen. 6th Gen was not far off 200 million total (albeit needing PS2 to sell well into the 7th gen to get there). 50 Million Wii's + 85 Million PS3s + 85 Million 360s = 220 million. That's about the size of the pie that PS4boneU will be fighting over.

OK PS4 may outsell PS3, but that will be at the expense of Xb one selling very poorly by comparison to 360. It won;t be because there's significant over all growth in the console market.

Hand held consoles are shrinking, and while they do more directly compete against mobile phone/tablet/iPod, don't think for a minute that mobile and tablet gaming isn't going to also affect home consoles. it will.
