Will there be no more in the future?

Well, I guess until there's any news to the contrary, yes it's the last one. I'm not sure if it was announced explicitly like that though - "last ever" or "no more in future" is pretty speculative.

I'd like to think they'd make more on another anniversary-like another benchmark anniversary like the 30th or 40th. It makes me feel old thinking about that though lol

Even in the curtain calls, some of the actresses made mention to the possibility of more, though there are none confirmed, and much of the posing, especially around the last day performance, made it feel like it was the last musical of this run. However, they also felt that way with the original SailorStars musical, but it was brought back due to popularity, so anything could happen! As a side note, I feel that if they do continue from this point, there's a chance they'd do another total senshi-recast.

However, even if they don't continue with this run, I definitely agree with Cosmos in thinking that they're likely to revive it for the sake of future anniversaries. It'll be interesting if they do to see if they do another total reset of the story, and if so, whether they keep the takarazuka-style or not.

YES! I would really be curious about this too! I feel like the fem!Mamo is a bit of a sign of the times, aesthetically as was the male casting of the previous runs.

Ah, I'm always looking forward to what the future of Sailor Moon brings though, whatever it brings. The revival really has made me feel hopeful about it, despite knowing it's unlikely to go on into my old age haha.

According to this tweet: https://twitter.com/ryuusagi/status/850509400930439170 they are planning more musicals and it will continue beyond this year.

I don't know how I hadn't seen that, seeing as I follow both him and Osabu on twitter! I'm a bit concerned though, because that's from April, so likely from Houston, and there was a lot of confusion around that time (such as people thinking LMF was for sure being brought to the US)... but it is in Japanese rather than English, which makes it more reliable. In any case, I hope it is!
