I have to say Infamous Second Son Sold me on the PS4 but now I am actually more excited for the Order1886.

Infamous and Killzone series are both spectacular. After how good Mercenary ended up I have to try Shadowfall. If you have a VITA you should pick it up. Biggest technical achievement in a very long time from a portable standpoint. Completely solid multiplayer and very entertaining cash and contract system that carry over to singleplayer. Graphically, Second Son looks the most impressive out of all next gen games to me at this point. The gameplay of the 1st 2 in the series was superb.

Killzone. ^^

Just the Brand sony sold me the console and the fact that ND is going to make something for it on top of other developers.

Kill zone.

The same way it sold me on the PS3, Final Fantasy Versus XIII XV.

Kingdom Hearts III, but I'll buy a PS4 until FFXV is released

Killzone Shadow Fall, Infamous and lastly Driveclub.

For me??? Driveclub.

Microsoft and the Xbone 180/720 sold me the Ps4, also in my country Playstation is bigger, so more games, better price reductions etc.
