Hello there,
1. There won't be a gallery, if one is made it will be for just non repeatable scenes.
2. Starcon will have more content, but this is unlikely to happen. More since Anna raises to top 1 and is already pretty popular.
3. Some specific costumes have special interactions/events and other will be done.
4. This would make no much sense since her subs can already see this kind of pictures.
5. This happens in a way at the park but is a possibility that can happen, not impossible but is not something that's worked.
6. Won't be done, as explained multiple times, this would require a lot of work since the assets for all possible combinations and scenes for them would have to be made.
7. Starmaker is a side project, after done there will be a rest period and a different side project will take its place.
8. This would be just a remake of the biki minigame, unlikely to happen, but it could open specific scene like the specific outfits do. (This doesn't mean that it will be done)
9. There are already scenes with girls at the hotel, as for animations, this WON'T be done.
10. Unlikely to go into extremes, and in regards to the "put to sleep", starmaker won't have non-con content.
