People want CoD, GTA, Destiny, Need for Speed, Fifa. 3rd party games. That's why PS4 is selling even with few exclusives: they don't matter, they are just an extra. People want a box to play all games.
Don't get me wrong, a lot of exclusives have sales potential: Mario, Halo, GT, and many others. But people won't sacrifice their 3rd parties. Sony got the upper hand so many times because they understood that securing 3rd parties will get you the victory.
It's a matter of logic: everyone that does a game markets it. Sony uses their budget to advertise their games, Nintendo to advertise their games. But all 3rd parties are doing the same, and that means advertising a PS4 or X1 game that will move units. It's like we could sum up Sony/MS advertising budget with 3rd party ones. And when you have a GTA putting 150M+ on advertising and a Destiny franchise that has 500M of budget for the start of the series.
