Sadly the chances of that are slim. Having 2 whole seasons with 12 episodes each means they will stay by that schedule cause the quality needs to remain constant. You'll have to hope for a reboot if you want them to keep the material unedited. Even if they do skip out on a lot of content, they will still get sales and still bring more fans into buying the LNs. They could even pull a Maken ki! 2 and just make a season with nothing but the fan service and it would still be a win-win cause they established among the anime-crazy viewers that it is that kind of series plus the Art is better in DxD anime no offense to anyone.
