I want to ask this since it relates to Dxd in a way because the Anime series lag far behind the Light Novels is this done on purpose because the production costs are so expensive or is it something else.

The reason for this because I see a similar situation to a series that I like a great deal called "A certain Magical Index", and this series is even longer than Dxd in length in the Light Novels not even Dxd approaches it. This series is at a standstill because they should have released the third season already a long time ago but they only recently released the second season, and it is lagging far behind compared to Dxd.
