MGS5 and Fallout 4 (probably will be released holiday 2014).

Speaking with friends, I definitely get the sense that Titanfall is THE system seller on the horizon. Lots of people telling me they will purchase an X1 when that game releases

I like MS, Sony, PC, and Nintendo all, but...Sony exclusives...Sometimes outnumbered never outgunned. They never disappoint.

Yes, but which one?

/EDIT...sorry not paying attention.  Infamous second son will be a system seller.  Game will sell 3.5-4.5 million. It will increase PS4 sales by 800K.  the Order will move some systems as well.  It will sell 1.5 million.  It will increase PS4 sales by 150-200K

For me Final Fantasy used to be the system seller before. Now it's just any other good game.

For PS4 that one seems to be Infamous: Second Son.

It definately seems like the best game on the horizon for the PS4.

Also if Titanfall ends up being great and eventually coming to PS4 it will sell huge and sell a ton of systems, especially if it is after a price drop occurs.

X sold me on the Wii U.
I want Titanfall but will play that on my PC

Mario Kart 8.
