Why I don't think the PS4 will pass 100m

[Intrinsic]

A lot of strange predictions/reasoning in this thread. Well, I am convinced that the PS4 will pass 100M. Here's why;

1. This gen isn't going to be as close as last gen. So if the PS4 sells 80M and te XB1 does 60M and the wiiU does 40M, that would mean there are people that would have bought an XB1 in particular that will buy a PS4 instead. This will boost sales of the PS4.
2. My above estimates are being very generous to the other platforms.
3. Last gen wasn't a 7 year generation because of power, it was a 7yr generation because of costs. This gen will be at least 6yrs and the new consoles coming out in the 7th year. Which will be at 2020. 
4. Taking the 7yrs into account, most important is the cost of the consoles. Unlike the PS3, sony is actually making a profit on selling the hardware. And the hardware is at $400 not $600. This means that by the end of the PS4s 2nd year on the market it would most likely be at $300. It took the PS3 5 years to get to $300. By the PS4s 5th year, it could be as low as $200. This lower cost of entry and faster potential price drops is actually the biggest point here.
5. We will have a pricing war this gen like we did in the 6th gen. In the 7th gen MS made a quote "we officially hd a price drop when sony announced $599". And sony spent the whole gen trying to attain price parity. This gen, especially if MS keeps losing like this, they will do what they did in the 6th gen and keep slashing the cost of the console. This will force sony to respond in kind (again like it was in the 6th gen). So we will have $199 consoles a lot sooner. At that price, there really is nothing stopping the PS4 topping 100M
