From my understanding there is a rumor that Tachanka is getting a complete rework from the ground up. This rumor came from a Youtuber at an event and has not yet been confirmed by Ubisoft. Also as of my knowledge Favela is being added back to the casual queue and is not taking the spot of any other map. Operation Grim Sky will be released on September 4th, which is the same day as the BFV Open beta start, not sure how this will affect the play rate of R6. If you have anything else to add please comment below with it.
