Don't worry, volumes 5 & 6 can be accurately adapted into 12 episodes. The only thing is we won't have any slow pace like the start of season 2, it'll be in high-gear from the first minute. Not that that's a bad thing, far from it. TNK knows DxD sells a ton and will do their best to not screw it up. If there's a few scenes they can't add, that's what the BDs are for. A season 4 is highly likely if you ask me (that, will most likely need to be 2-cour, though).
