Microsoft’s consoles has always been a brand magnet, it has worked Activision for its present consoles and received a lot of acclaim.
There has been news in the air nowadays that EA wants to enter into a deal with Microsoft, just like companies did so successfully in the past. We might get to see a game being exclusively produced for Microsoft next generation console that might get some fans more interested. Things like this always carry a lot of ifs and buts, but stranger things have happened in the past so it might be a good bet.
The game that is speculated to be exclusively made available for the next Xbox is Battlefield 4 if the deal is made official. But this news can only surface if we have an authentic news about the two giants coming in a contract.
