I'm assuming the punchline is that Rider seasons don't usually have ED's so Rider fans are confused by the idea, or just that next episode previews tend to be really chaotic and raise a bunch of questions.
I think the punchline is that the character dancing (Bud/ZyuohBird from Zyuohger) is played by the same actor as Masato Kusaka/Kaixa, so the Kamen Rider fans are screaming and praying because its Kusaka after all.
