Call me negative on this, but I'm not all that high on Gunn running the creative of DC. James Gunn is great, but his history of films and shows made are ALL very limiting in appeal (GotG aside, and even that franchise wouldn't have done as well if it wasn't a part of the MCU).
Hopefully he learned enough from Feige and can put his personal preferences aside for the larger Universe. Also, this 100% means that a sequel to TSS will get made now that the director is in charge of the studio. Not that that's a bad thing per say, but they also need to be making highly accessible four quadrant films.
