It wouldnt surprise me if the DS games linked up to a Rev version of pokemon (wirelessly of course), maybe using the DS as a controller or view finder as well as a means to trade pokemon.
But what i dont like about the pokemon franchise is the inclusion of more and more pokemon, the original games (red, blue, yellow, green) were amazing and realy enjoyable to play, and it was actualy fun trying to catch all 150 (or 151) pokemon. I lost interest when they started adding more and more pokemon into the newer games as well as different types, i found the original games easy to understand and play, yet i found the newer games more confusing due to the extra pokemon and extra types.
I support a mass culling of pokemon!
