"That feels way too long"
I mean, no, not really?
Piranha Plant was worked on alongside the base game, and we've already seen that Joker and Brave had data on the release day disc, meaning that they at the very least had planning stages ready to go.
And I don't see how "Brave = Banjo" at all. The only connection is they start with B.
I could understand having a codename ready, but I highly doubt that 2 months away from release, plant, joker, and Erdrick or a third character were worked on. That was when the rumors for a square rep and Minecraft starting circulating. Leading people confused because box theory gained a lot of traction then. There is no way joker and brave had models then. Plant still needed to be polished although it was pretty far along. We also know from the reddit beta tester leaker plant was the only one in working condition. Neither of the other two characters had physically signs of existing.
Meaning they weren’t ready for beta testing which they certainly shouldn’t have been at that time. But the point is those rumors shouldn’t have known any specific character at that time period. If anything maybe joker but as we saw that wasn’t the case.
With how tight secruity on the pass is, stuff leaking that early doesn’t add up to me. As for the brave equals banjo thing though. The codename itself doesn’t seem to be obvious, but we only have two other codenames to work with. Jokers was a symbol, and plants was it’s actually name. For all we know brave is a description of a trait the character has or something else. My main point for that was that people thought the stars worked for banjo especially the side or whatever it was brave had. Which I’m not saying he is brave, but I could see it.
I do find it interesting though when I think about it how Jon from GX bought up how banjo was likely the second character and that he thinks chrono trigger is coming to switch.
That’s just a side note but something I thought about that could be neat. What if there actually is a square rep and it was chrono? Two classic third parties as E3 choices would be pretty nice actually. But that’s just something random and unrelated to the previous points really. I’m heading to bed though.
