More detail if anyone wants (translation was kinda rushed, so corrections by Jop or B are welcome if necessary.) :

He's been really busy every day, mainly with writing DxD (hmm, maybe v20 will be out in August after all). Perhaps because of the anime broadcast. Second act of SLASH/DOG coming soon.

DxD 1-19 + DX.1 will get another reprint.

Talking about the anime bringing in new readers, that he's grateful for being able to publish 20 volumes (DX included), and I think readers have been requesting e-books of DxD more and more.

Just mentioning that this month's short story will give the spotlight to Tosca (apparently Google Translate approves of Tosca as the correct translation now ) who first appeared in v19.

I'm not entirely clear on this, but some sort of newly-written content for Fantasia Bunko will feature "Team DxD" associates from the Norse myth (Nice). Not sure if it's a crossover or a 27th anniversary thing or what, but it's called "Kingdom Fair ". It's unconfirmed whether it will be recorded in DX or not (I hope so, since they're covering all the SS's, even those on the back of posters).

Ishibumi will be making a guest appearance at some sort of a Fantasia Bunko breasts broadcast event on May 19th! Heavily featuring DxD, livestream link. Definitely watching that when it airs.

Issei vs Diodora will happen and look forward to their voice acting during it. (Also that Shalba is one of the best villains in DxD)

Akeno and Koneko's development will still happen in the 2nd half of the season, in particular Koneko's. It will be handled better than the LN's when it comes to Kuroka.

Rossweisse joining the team will be more natural and not as forced. Although the scene of Rias persuading her to join won't be changed.
