Me too, especially because that means DxD would make anime history by being the first Light Novel to have it's entirety adapted to anime form.

That's something only series like those in shonen manga have managed to do. Unfortunately, this would be incredibly hard to pull off unless Seasons 4, the planned Seasons 5 & 6 do well, and then every season after manages to do the same.

Essentially, each season would need to have the same results as the first two, meaning they'd have to do this successfully about eight more times and make almost no mistakes.
