The character could have been decided on January 2020 at the latest, but maybe, unlike the others who probably already had work on conceptualization and with how complicated the FP2 pass characters were, they perhaps took time with licencing, agreeing and such putting them in that awkward spot.Yes, although that character got decided on in January 2020 at the very very latest, even sooner if the Byleth presentation was recorded even earlier, which I think could be enough time to work it into the schedule to have the usual three month gap between characters after Kazuya.
Hard to tell honestly, I just think the supposed big gap isn't for nothing. Either that character bring it's whole game with it, and is the most complexe mofo around, or he was a late addition to the plan
