Turns out that the same technology used in Personal Trainer: Walking to train you will also help you train Pokemans in Pokémon Heart Gold and Soul Silver. According to Andriasang, the Pokémon Sunday TV show revealed a new pedometer device used in the game, called the "Poké Walker," that resembles a cross between a Pokeball and the Pokémon Mini handheld. For some reason, Nintendo decided to make another wireless pedometer peripheral for the DS rather than allowing people to use the existing one.

The device allows you to build one Pokémon's experience and personal affinity simply by walking. In addition, the Poké Walker generates "watts," which can be used to catch wild creatures and find tools inside the Poké Walker world to send back to the full game.

Check out the first screens of the remakes in our gallery, as you come to the terrifying realization that Nintendo didn't mention this game at all at E3.

hmm interesting, I was considering Personal Trainer Walking, but this looks alot funner

Cross-over gaming appeal -- exercise and Pokemon.

That is something I might have to get.

The sales for this game will be ludicrous

Like Platinum's?

They will put Platinum's to shame.

(>'.')>

think about sales will reach the following demographics

Pokemon fans (new school)
Pokemon fans (old school)
Japanese people (all)
exercise junkies
Wii Fit (casual excersise crowd)

I predict sales of 20 million

Like 7.5 million units in one week :P

interesting but i like pokemon exactly the way it is, or Platinum is.

Seriously though, increased casual/fitness appeal (all the rage), revival of beloved classics (luring in a lot of ex-Pokemon gamers who have set out the last few), the fact that Pokemon is becoming increasingly popular with kids again (it's ridiculous, though not as much so in the 90's), higher DS userbase....
Yeah. At least 20 million.
