I just caught up to Ryce's post (that i'm screenshotting so he doesn't get pointlessly quoted):
So it does indeed sounds like the missing character is Incineroar, and that there are some characters in the banner that are the real deal based on his set of infos.
So we're dealing as a solid base of Incineroar + Ken is and fair to assume one more character from the banner in.
Going by how Vergeben is sure about a Square Enix rep, Geno is a safe bet, but I'd assume Shadow as well if only for his status of the easiest echo ever. Then you've got Isaac which possibly had an item leak already.
I think it's the end of the road for chorus/banjo/mach rider
