Read OP. OP says exclusive. Call of Duty is not exclusive, nor are any of these.
If you read the OP now, it's also being reported that it will be FIFA.
Hmm...I would say it has to be Fantasia, Ryse, or Dead Rising 3. Those are the only third-party XB1 exclusives, right?
It says an unannounced 3rd party exclusive in the CVG report.
