Caladuz
It's probably just a joke and he is implying that a vague picture (just like him meeting a voice actress) could be interpreted as evidence for anything.
He made this statement one day later:
"I'm being vague on purpose. I have heard a few of people's requests from my sources, but if I have literally heard nothing, I actually haven't ever heard their name ever pop up as a confirmed choice.
I.e. professor layton, banjo, xenoblade characters, and a few others are all characters i will just say are all characters I haven't heard from my sources. Other than that, no one has guessed a confirmed character in this thread."
It's interesting he didn't mention Phoenix Wright, while he disconfirmed Prof Layton specifically. Maybe this is a good sign for our lawyer.
