I also wonder what that "idea" will be. But Jason Fabok's art alone is reason enough for me to buy the comic. Look at the hair. It's THERE.
It's kinda hilarious that Jason, Dick and Slade get a buzzcut almost at the same time. Is this some DC insider joke? When did the joke start? With Batwoman after shooting Clayface? James Gordon as Batman? Gotham Girl? Arkham Knight Tim Drake? Batman #666 Damian Wayne?
And who will be next? Barbara Gordon? (Barbara always seems to have the same hairstyle. In the meantime Dick Grayson, Jason Todd and Tim Drake have had a lot of styles through the years.)
