I still think Sephiroth will drop Christmas Day
...But, let's play devils advocate for a moment: People have been looking at the awkward timing as it meaning something to us westerners because it's so late in the day this time, but what if we've looked in the wrong direction?
It's 5pm for us, but 7am for Japan. So if hypothetically a shadowdrop happened, that'd give players in Japan an entire day with the new character. The last time a character shadowdropped, it was like, noon in September 2019 for Banjo-Kazooie for us over where, and Japan I think it was super late at night.
It almost makes a twisted sense since Banjo is a big western pick so we ended up getting them at a reasonable time, so what if they were to reverse it. Even though Sephiroth is universally known, he does originate from Japan
So what if that's it? It's going to be an early morning drop for them this time? Heck I remember when Joker dropped late at night for us but early for them too
