So here are the new IPs in case you can't remember them all: 

The Order 1886, Driveclub, Knack, Project Spark, Ryse: Son of Rome, The Crew, The Division, Deep Down, Sunset Overdrive, Quantum Break, Dying Light, Mad Max, Watchdogs, Destiny, and Titanfall.  (If I forgot any let me know)

The game that I think has the potential to be the biggest is The Order 1886.  It is being made by Ready at Dawn and they have a great track record of making amazing games, I know this is their first ever console game, but they have been working on it since they finished the last GoW game on PSP and I think they can come up with something really special.  I am very interested in the premise of the game and I can't wait to see some actual gameplay.  The reason I didn't choose Titanfall or Destiny is because I think the market will be too crowded with FPS games and I don't see one of those rising above the rest.

I believe Watchdogs, Titanfall and Project Spark can become quite successful.

Destiny. TitanFall could have had a chance, but EA thought it was a smart idea to make it a timed exclusive. they will regret it though

From what I've seen thus far, Destiny or Titanfall.

Titanfall....

Or maybe Project Spark

Anything made by NaughtyDog.

Destiny or Titanfall

probably Destiny though because PlayStation fans wont be able to buy TitanFall when it releases

and are you sure that "The Division" is a new ip?

Ya I'm pretty sure.  

I think Titanfall will also have the benefit of a monstrous marketing budget thanks to MS.

For me I believe Watch_Dogs, Destiny.
Third Party IPs will continue to dominate
