Not to suggest credibility, but "imminent" is relative, isn't it? In the same way "soon" can be later this week, or not til next month, imminent could be tonight, it could be tomorrow, it could be in two or three days.
I feel like you bring up Byleth way more frequently than anyone else these days. Usually to talk about how often we talk about them.
I personally don't think we've talked that much about Byleth recently. They're mentioned, sure, but they're not really the centre of conversation like they used to be. You weren't here when that was happening.
The reason they aren't that impactful to the game is because we've already had a lot of content from that series, and it's not like they were some longtime fan request. And, 3H is, all things considered, rather small potatoes compared to someone hailing from an entirely new, potentially big, third-party series. They're only impactful to our conversations because they're contentious.
