Today's news (well, this week's at least) is that a new UI for BF1 will be supported in Battlefield 4 as well. This will likely just be for social aspects and game control (settings etc.) and not actual combat - that slick new minimalist combat UI will have to wait. This will be out for BF4, and then launch with Battlefield 1. It will come to Hardline after the Battlefield 1 release. Post-release, you will be able to move between all three games from within the same UI. As we know from my recent post on the Battlefield 1 blog, web browsers are being phased out for Battlefield 1. This means we will be able to move between games from the same client without Battlelog - an intriguing possibility.
