According to VGC CoD has been on a huge decline while Battlefield has been on an increase. 

i think this year when COD returns to regular historic scenerio it will do extremly well. im very much enjoying IW

After AW I'll personally never buy COD game made by Sledgehammer. 

Can tell you these numbers most likely aren't right.....cause BF1 isn't that close to IW.

Impressive numbers for battlefield and cod on ps4. Battlefield definitely catching up to cod. Don't think we will get another battlefield mainline entry until 2019. So the next big battle is then.
