Hello there,
no worries, I always pass couple times a day.
In regard to the outdoor photoshoot, even though it seems like is in the middle of the street or in plain sight, it's meant to be hidden (except for Gabriel's house which is done right inside with him). While there are some "public" scenes like the nightclub and there's the sex at the park, there won't be full public sex, there will be more places for the photoshoots and the current ones MIGHT be expanded, but there won't be full public stuff.
For the studio, Adrian can already appear when Anna wears the teacher outfit. As for others to join, there's thoughts to add another character to the studio invitations but that would be the only extra outside of the ones that are currently available. However, there might be other scenes added for the current ones. In the future is possible Ken will be able to be invited even on Sam's route, so that he has both routes available at the same time.
There are no plans to modify the vacations outside of the solo route that is in thoughts for JP together with some content for Mei.
Starcon got reworked and might have some extra content, but it is undecided on what will be or if there is more content, since this is a "slut route" content and love route needs some content to balance things out there most likely won't be much increase on that until love catches up.
Anna will get more share content as always, but Anna will not be shared with Mario.
The gas station, farm with Robert, and the livestream option are things that could happen. Just of course, as always, no guarantees on that.
The park extension, same as before, is taken as "hidden sex" as the plan is not to make it into a "public" thing. The beach is one of the exceptions on this rule.
