I think that’s to be expected, I would like a proper send off though, I feel like if there even is a next one it would be the last, considering the reason it’s postponed appears to be internal disagreements (according to DeepL) so it seems like they’re not able to do what they want anymore, and I don’t think they’ll be able to do so in the future (whatever it’s because of age or regulation.)
Las Vegas kind of felt like an attempt at one, it featured a lot of past clips with the betting essentially being a clip show, but it really wasn’t up to a “final” episode. I remember the betting made up most of the show was really boring to be honest, maybe a Batsu with some callback gags could be better, maybe not as a straight up 1:1 of those gags, but adapted somehow?
I believe it was the airport batsu, and the portraits may have only been Hamada.
I think it was in the earlier parts, probably within 3 to 5. I do remember one of the artists being Man Gatarou, he’s the artist for the NATSUMIIIIII one. He’s a manga artist who did a few manga (warnng though: very trashy in both art and subject matter.) Some of them are being translated on Mangadex if you’re curious (Crime & punishement, and happy heart company are the two I know of)
I do believe there are sub notes about each artists so you can find out about the other ones that way, I think one is just credited as street artist though.
