I wish the last playable character would be female, to mix things up. I would love to see Sypha but that's not gonna happen if Cox already confirmed she's not playable. That leaves us with Sonia, which is probably the least known Belmont for various reasons, so she's unlikely too. Mercury Steam can do whatever they want though, so Shanoa could be turned into a Belmont too. But something tells me they won't do that either.
I guess the character is, in fact, gonna be Richter. I hope the Belmonts in this game won't play too similarly. What if they'd give Richter a sword? Naah.
Maybe Grant DaNasty is a Belmont in this game? He could use knives and climb all over the place. Hmm.
