PS4 games releasing this year:
Horizon Zero Dawn, Final Fanatsy 15, Kingdom hearts 2.8, Uncharted 4, Ratchet and Clank, No mans Sky, Mass Effect Andromeda, VR + games, Mirrors Edge Catalyst, Dark Souls III, The Devision, Doom, Hitman, Mafia III, Kingdom Come, Street Fighter V, Deus Ex Mankind Divided, the Last Guardian, Overwatch, For Honor, Persona 5, Gran Turismo Sport, Detroid, Dishonored 2, Ghost Recon Wildlands, new Fifa, madden and co, Nier, and even more.
+ Older games that are already available like: Witcher 3, GTA V, Metal gear Solid V, Batman Arkham Knight, Dragon Age Inquisition, Bloodborne, Rocket League, Minecraft, Battlefront, Until Dawn, Driveclub, Fallout 4, The Last of Us remastered, Destiny and much, much more. Some of those games are already pretty cheap.
Even with Zelda U, 3D Mario, 3D Metroid and F-Zero on launch i really cant see Nintendo to be able to compete against THAT in any way. There will probl some Nintendo fans that will get the system (same people who bought a wii u) and thats it.
I also cant really see third party support happen. They promised it on wii u and it failed horrible.
