Apparently there's been talk of a SK pinball game? Not sure exactly how that would work out? I also saw more about how SK7even is going to be more on the serious side and characters that had certain things happening to them in pbs are going to continue in SK7.
"About
Peach Ball: Senran Kagura, Takaki-san can’t share much yet, but the plan is to have the
Senran Kagura girls lay down on the pinball table and have the ball bounce off certain key areas on their bodies. It’s going to be a full-fledged game, unlike
ShinobiRefle, which is a smaller title created to showcase what the team can do with Nintendo’s console."
"After having explored multiple genres, Takaki-san would like to develop a dodgeball game next. Another genre he would love to work on is 2D fighting games. Again, we asked him if he’d like to collaborate with Arc System Works as an example, and he seemed quite appreciative of the idea. For that kind of game, he sees PC and PS4 as ideal platforms, and he’d also like to work on Xbox One."
"Moving on to
Senran Kagura 7even, it’s going to be a continuation of the story after
Peach Beach Splash. We can expect to see the changes and evolution for some of the characters hinted in the third-person-shooter extend into the new game, which is going to be more serious and dramatic.
Estival Versus and
Peach Beach Splash had a lighter tone, but
7even is going to be more similar to
Shinovi Versus instead."
"About
the mobile game Senran Kagura New Link, Takaki-san confirmed it is the first in the series which has JRPG elements and also has a gacha system. He feels mobile games have incredible capabilities of portraying stunning 3D characters and wanted to create something that would allow more people to get a feel of the
Senran Kagura series— in the hope that they would then move on to the actual console games. That being said, he’d also like to release
New Link in the west. He thinks that fans of the series would be pleased since the graphics are really nice.
Considering that Honey Parade Games has been working on several titles at the same time, Takaki-san revealed that the team has been expanded slightly as of late, but not too much. Interestingly, he teased that there are actually going to be more game reveals in 2018, created by the team and a different new producer. Next year will be “really exciting.”"
