A little late, but more was revealed on the game recently.

-Pikachu likes coffee and tea (mostly coffee).
-Apparently, he has a thing for women/girls and is really weak around them.
-Pikachu isn't even the head of his own agency. It's someone named Mike Baker
-It's Tim that interviews people while Pikachu interviews Pokemon
-Interestingly enough there's quicktime events in the game. It doesn't from this point have major story effects, but will change how the next scene plays out is all.
-Detective Pikachu is slow and can't move very fast.
-Detective Pikachu can't use any moves (though he can generate electricity. Just not use things like thunderbolt or even shock.

that's about it on all the news other than names of people who run various shops or businesses.

More and more I see this info I think my theory is right (the original first theory - Human to Pika PMD like story). it'll be funny if it is because I had people laugh at me for the theory on YT and you know the usual hate thing that comes from there. Though since then I've seen more people turn to the theory as well. The best part is....it fits perfectly. The title "Birth of a New Duo" even means there will be more (so we may not even find that he WAS a human in this game if so....maybe just have it hinted at.

lol I need to start trying to work on a banner/sig for Detective Pikachu or something, my hype for this is still way too high xD. Guess I'll get my old CS3 out and try to start working on something whenever good renders come out to use. Just I like Pikachu and mysteries too much...to have them (confirmed) together in one....is too much lol
