They're working on a detective game featuring Pikachu as a partner. This game has an alleged development cycle of 2 years, with release expected in 2015. A rare Pikachu is said to be the enemy within this game but they can't see people liking it. The game is to feature a special Blue Pikachu, which talks. The Pikachu is being controlled via motion capture and facial recognition
All this information is from early development, so it is probable that it will change should the game come out
!
It was revealed that a new Pokemon Detective (working title i think) game is being worked on we were shown images of the Pikachu face recognition pics but didn't know what the game was.
I…um...yeah I am skeptical about this but I will reserve final judgement for now as it is still in early stages.
