A brief post has appeared on the PlayerUknown's Battlegrounds site that acknowledges that PUBG Corp is hard at work on some significant changes coming to the game's maps and loot balance. Currently, the Erangel map is in the process of being retooled, something that is designed to keep older content as relevant as new content.
We understand that loot balance is a very important part of the game but also recognize that the map layout is just as important, so we’re working hard to ensure that any changes made to either will feel good when completed. We plan to start testing several potential changes to Erangel soon, and will share our plans for these tests in the coming weeks.
The post was made in response to leaked images, but devs warn that these "are usually just a snapshot in time and rarely represent the entire plan or scope of what's being worked on". Further, the team is excited to show off what's being done and to test it "soon".
