Have to say I agree with this article, As a owner of all 4 gaming platforms, PC, XB1, PS4, WiiU. I have this to say. Ever since Launch, what were the games that killed the competition for the PS4? PS4 has had the 3rd best line up of games this gen excluding Bloodbourne which has only just been released. The system has been riding a wave of success for unknown reasons since launch. The games are no different to what's on XB1 and PC yet falls short on 1st party exclusives but continues to dominate the market. Lets look at some of the most popular genres here.

Now iv only mentioned some of the most popular genres here and its clear that the PS4 is lacking in games and quality. The PS4 is selling but its not selling because of its better games. I am still a little unknown with the WiiUs game lineup but I reckon WiiU has the bases covered especially in the platforming genre.
E3 is looking like XB1s best year of gaming, WiiU has some Gems coming out while PS4 is hiding in the shadows with no high quality franchises we can think will come out anytime soon apart from God Of War 3 RM. However the PS4 will continue to outsell the opposition regardless of its games.
This is what baffles my mind the most. PS4s more does not equal better. What ever 1st party game you buy on PS4 there is more of a chance theres a better counter part on another platform.
