Writer Gail Simone tweeted an image from artist Yildiray Cinar showcasing the "Black" Firestorm Jason Rusch alongside the "white" Firestorm Ronnie Raymond, lighting it up with their powers.
No word on the plot point or what is happening here, but it shows you the almost "mirror" approach the title is taking with the two lead characters.
