Don't worry Anon, if my Two Timelines Theory is correct, then it's most likely a mare video, since the whole Cadance-Shining-Chrysalis dynamic doesn't exist in the stallion timeline.
Although him and Cadance appearing as their normal genders could throw a wrench into that, there's still the simple possibility that Trixie manages to fix the universe before or during this coming episode.
Of course, there's also the possibility that the scene featured won't even appear in the next episode, and it's just a fun little bit Tamers decide to release on Twitter.
Point is, don't worry your pretty little head over next week's episode, cuz it won't be a stallion-focused one. I promise.
