According to their official Twitter account, Electronic Arts DICE, the developer of Battlefield 4, is looking into the possibility of allowing players to move their statistics and progression from the current generation version of the game to the next generation version.
The Tweet states that;
We've heard reports that players would like their stats and progression to transfer from current to next-gen in BF4. We're investigating.
Unfortunately there is no more information other than the short blurb in the tweet and we will have to wait for more forthcoming information from the developers concerning this feature.
Battlefield 4 is due for release this coming October 29th for Windows PC, PlayStation 3 and Xbox 360. It is also slated to be a launch title on both the Xbox One and PlayStation 4.
