Right now, for every three Play stations sold, two Xbox Ones are sold. Sony stepped up big time, and has answered many questions people have had. Microsoft has also made people heated with things like game sharing, offline restrictions, and more. Sony has also had some issues, but have been communicating with the community as much as they can just like Microsoft. In my opinion the PS4 will have more sales for some simple reasons.
-Games will be able to be traded
-No spying on you with connect.
