Get the PS4 imo. PS4 has and still gets the best multiplats as its the strongest consoles right now. As well as exclusives like Killzone, uncharted, last of us, Knack, the order and the last guardian etc. from sony.
And as the xbox 1 is selling horrible in japan the sony console will probably get every strong japan focused game exclusively like akiba strip is for example. As well as exsclusive indie titles and free to play games due to Microsofts own policies.
