I want Metal Gear Solid 5, Persona 5, Tales of Zestiria/Berseria, Yuro No Nai Kuni and Atelier Sophie, but all of them are coming to the PS3/Vita so I don't have a need to buy a PS4.
Nothing from XBONE interest me so I also don't see the need to buy one.
Right now I'm happy with my Wii U, 3DS and Vita.
