It seems like a High School DxD Universe is really going to happen, well not really official yet but:

Ishibumi even commented on the MCU and DCEU, and jokes on the shorten name as D×DU. Well either way he says if he ever does another work that takes place of the DxD world, he will probably go with the High School DxD Universe name.
