Nintendo is working on technology where Pikachu can mimic facial expressions using the 3DS' internal camera.
Japanese TV channel NHK (via NeoGAF) showed a teaser of the title, with more information scheduled to be released next week.
Screenshots of the broadcast show the title using the 3DS camera to capture the movement of a user's head, eyes, and mouth, and then map the changes to a model of Pikachu. The software is said to also capture a 3D model of a player's head.
The end result of the technology will be featured in a TV interview with Pokemon Company president Tsunekazu Ishihara, to be broadcast on October 28.
Pokemon X and Y, which was released for 3DS on October 12, has now sold over 4 million copies worldwide.
