Never on 18 September 2014
I have a 360 and Wii U and currently see see very little to entice me to buy a ps4 or xbone. If you have the spare cash floating around, why not, if not it's probably best to wait until they get a more interesting library.
That said I wouldn't mind trying TLOU remastered as I didn't have a ps3. But I can easily wait for that one game.
