Pleasantly surprised to have learned this earlier, according to this tweet from the Dev, they are discussing the summer update in a Twitch stream tomorrow, and will discuss Xbox One X 4K support.
I had given up on this game & I thought that with BFV coming up soon, they were not going to enhance it....this is great news because the game already looks amazing as is.
Join us from on #Twitch on Jul 31 for an exclusive livestream where we'll discuss all the new game improvements in the #Battlefield 1 Summer Update including 4K support for Xbox One X and more. ➡️ https://t.co/KZHqGdlZ4Cpic.twitter.com/mbcRQklDIo— #Battlefield V (@Battlefield) July 30, 2018
