I've been wanting a pokewalker like accessory for so long, does /vp/ have any hopes or expectations for this thing?

I know it's stupid, I could just bring my 3ds with me, but I like the idea of having a tamogatchi like system that I can train pokemon as I take steps and then transfer them into a game. They could do this through a phone app, the 3ds itself, or sell little tamogatchi ripoffs and make millions.
