Yesterday it was reported that Battlefield 4 will not support cross-gen play and all versions will have separate careers, however it appears that DICE has decided to reevaluate this decision.
Following some anger from fans yesterday over the announcement that current-gen and next-gen careers will be separate, the developer has announced that it is currently investigating the possibility of allowing statistics to be transferred to the next-gen version of Battlefield 4 once it is released.
We’ve heard reports that players would like their stats and progression to transfer from current to next-gen in #BF4. We’re investigating.

This seems like the logical thing to do with a game with such a major online component. There’s no point pointing hundreds of hours into the current-gen version if the next-gen version is going to release a few months later forcing you to start over again if you want to buy it.
