I think PS4 will certainly pass 17 million by 2014. And I guess it will be shipped 20 million units. Its crazy they way PS4 is selling.
I know this has been discussed a lot of times. But I wanted to discuss it again. Sony have stated that they want to sell 17 million PS4 by April 2015. I think there is a small chance that PS4 might beat their expectations again.
This holiday will be huge. Sure there are less games compared to previous years but now there will be more focus on games. Destiny has the potential to be the biggest launch for a new IP. GTA V will be in PS4 with exclusive contents (multiplayer perks or DLC, who knows). Farcry 4 will be a big seller and has PS4 exlusive features. Little big planet 3 and driveclub wont do anything sales wise but will add variety for having games options.
I think there is a very good possibility that PS4 will cross 15 million numbers by 2014. And if everything goes right then it might cross 17 million numbers. It is possible for PS4 to beat expectations again.
PS: I request you guys not to derail the OP.
