Based on the huge pre-sales for Pokémon Diamond and Pokémon Pearl, Nintendo expects them to be among the top-selling games for all of 2007.

Pokémon became a nationwide hit in the United States in 1998. Now a new wave of Pokémon excitement is on its way, complete with more than 100 new Pokémon characters, the ability for players to battle wirelessly on Nintendo Wi-Fi Connection and voice-chat abilities, which act like a cell phone but with connection among friends only.
