That's a difficult question, shooters are generally more popular then 3rd person action games and 1/3 of every PS4 owner got Killzone: Shadow Fall. But InFamous: Second Son is the best looking game (on any platform) so that will help sell more copies of the game.
My final bet is 2 million after 1 month but I hope it's selling better. (undertracked by vgchartz)
