No you can not get a PS4 if you trade in your game Ghost. In order to get the PS4 game system you will have to pay.
No there are no plans to release a new slim PS4 model. The PS4 is just called the PS4 and not the PS4 slim. A model is called slim when a fatter larger device is upgraded to a smaller slimmer unit. The PS4 will not even be released until the 2013 holiday season
The PS4 from Sony is developed in Japan
You can go to the PlayStation store and download the PS4 version on your PS4
Since the PS4 has more feature and better graphics, In my opinion I would say PS4!
The Ps4 of course because it has much better graphics and the Wii U is a kid friendly and the ps4 also if you like sport games you will have to get a ps4 because the wii u doesn't have sports games if you want to talk to someone you can't do that on the Wii u only on the ps4.So the choice is a ps4
