I’m not sure that anybody has a “monkey brain” for finding any of this stuff interesting and plausible connected.
While I wouldn’t call it a safe bet to think this confirms the Chun-Li and Tales bit, I think it’s an interesting bit that could connect. Emphasis on “could”, because we just don’t know, really.
The only reason I think it’s interesting is because, well, people used the same suggestion that “they could change it!” with the box, but they didn’t. If there are 2 music slots but three voice slots (I believe there are files to corroborate this, at least that’s what I was told) I think it’s plausible that we get 3 new characters, one of which comes from an existing series.
It fits along with the Chun-Leak, but it could fit with plenty of characters. So it doesn’t quite send us in any direction yet. I think it’s worth keeping in mind.
EDIT: So as I have just checked, this is indeed based on internal files, and not simply the UI. Apparently 3 more particular characters makes a perfect square in Squad Strike, but that doesn’t necessarily mean anything. It’s just interesting to think about. (Thanks to
@Flyboy and
@Opossum for those tidbits I stole just now, lol).
