This game alone will sell millions. Then when they rehash it with updated features and release PokemonZ 18 months from now, people will rebuy it. selling more millons.
Not for nothng, the game looks amazing and the shift from the top down view to three dimentional is a huge welcome. What is the greatest bonus s that it goes all the way back to Kanto generation 1 Pokemon so they do not force the new pokemon on you lik Generation 5 did. As soon a you start out right outside your home town you can catch all the good old originals, caterpie, pidgey, spearow, weedle, pikachu, etc along with the new generation 6 variants.
