@Aspirety Maybe “full-fledged” wasn’t the best word choice; I just meant that it would be an actual Episode rather than a short story or collection of TIPs. At least, that’s what I think umezawa_report implies in the tweet.
(spoiler for my interpretation of the tweet’s JP text, click if interested) 新作エピソード (lit. new work + episode) seems like a strong term, stronger than just エピソード by itself. I also feel like 加えて出す has more of a connotation of “append” compared to a word like 付ける. And I looked around a few Japanese sites earlier but didn’t see the word エピソード used to refer to the content in Tsubasa or Hane. That’s the basis of my judgment.
Of course, it’s totally possible I’ve misunderstood. (Anyone else knowledgeable on the subject want to offer their thoughts?) Regardless of what words we use to describe it, we still don’t know how long it will be, or how important it will be; I’m also someone who felt that Umineko was complete after I read Episode 8. But the world of Umineko is deep and I’ve also learned to never underestimate it.
@Sapphire Good question. I personally have no clue, but the way I see it, after a ~5 year break, Ryuukishi is only starting WTC5 now because he feels like it, so I wouldn’t be surprised if he takes an extra Comiket longer because he feels like doing something else. The tweets are loaded with small phrases like “maybe” or “planning to” so I’m sure nothing is set in stone at this point. Maybe it’ll be summer Comiket, or maybe just Umineko “Hou” will come out then and it’ll be winter Comiket just 4 months later.
