In the long run, if you are a true gamer, you will have to buy a PS4 to play the amazing Sony first party games, masterpieces from Naughty Dog, Santa Monica, Polyphony, Media Molecule, Sucker Punch, Project Siren (a.k.a. Team Silent) and many others.
But that will not happen in at least 3 or four years, so, it does not matter for now. I have a Xbox One and it is AWESOME.
will buy a PS4 in one or two years.
