New RB and SB mechanics are being worked on and will be further announced.
Key ones that caught my eye was no HUD for friendly's and Enemy's and no markers for ground forces in RB.
Also if you are a simulator player, new country rotation will be worked on and further announced!

P.S. Comment if you think RB needs no HUD! :D
