A portion of a GamesRadar interview with Pokemon Company/GAME FREAK Board Director Junichi Masuda, and GAME FREAK Designer and Developer Takeshi Kawachimaru...

GS: Are there any specific plans for Pokemon on the DSi?

Masuda: We haven’t really considered it, but we certainly feel as if something fun could be done by utilizing the camera.

GS: Has any serious consideration been given to bring a core game to a home console, in his case, the Wii?

Masuda: No, we are not thinking of going into development for the Wii because we feel the core idea of Pokemon, communicating and trading with friends and other trainers, is best represented by being able to go anywhere and bring the system with you. This core concept of Pokemon is tied very closely to the portable system.

GS: Do you feel that at some point in the future when the online capabilities of a console system are more prevalent, that this idea of communication, trading and community could be done in a strictly online context?

Masuda: Yes I believe there is a potential that a home console might have a match for our Pokemon concept, but as I said the basic concept is that you trade, you communicate, you want to remain mobile. If that challenge is met by the home console, then we would consider development, but at this point the portable system is the best match for the Pokemon games.
