Infamous isn't a huge ip. Never has been. It will do pretty well because it has nothing else to go up against, but If it couldn't sell much to 80 million playstation fans, it won't set the world on fire to 5 million either... Titan fall is up in the air to me. If it goes any where near the popularity of cod, and gets the rep as the go to game for multiplayer, then it will do very well... Only time will tell...
