Call of Duty will sell more on PS4.

Depends on how COD will like on xbox1. It's confirmed that COD is native 1080p on PS4. Although most casual gamers may not know or see the difference if it's not 1080p and although short-term opening sale won't be affected, if xbox1 COD isn't 1080p then it may hurt sales in the long run.
