DICE announced that they will effectively scrap Battlelog for joining and browsing servers. In its place will be an in-game UI where players can join servers, much like it was for all previous Battlefield games up through Battlefield 3. This change will begin with Battlefield 4 and will make its way to Battlefield Hardline, and also be included in Battlefield 1.

The new UI in Battlefield 4 will reportedly include the following features.
A "recommendation engine to suggest maps, modes, and more.

"The new Battlefield user interface is designed to improve the experience of playing with friends and to bring relevant content to your attention."

The UI change is reportedly in testing by a small number of players and should be added to Battlefield 4 later this Summer. We have not yet seen images of the new UI in question.
