Pokemon Diamond and Pearl will release for the Nintendo DS this Sunday to retailers across the U.S. With just four days left to reserve (check your local retailers to see if they're still accepting preorders), Nintendo has announced that more than 533,000 copies of the game have been pre-ordered, more than twice the amount reserved when Pokemon Leaf Green and Fire Red were released a few years back. Those titles went on to sell more than 3.4 million copies. Based on that historical sales data, the huge success of the DS over the past year, and the massive amount of Pokemon Diamond and Pearl sold in Japan, Nintendo expects the two games to be among the top selling games for 2007 in the States. The official press release follows:
Pre-orders for the upcoming Pokemon Diamond and Pokemon Pearl video games for the portable Nintendo DS have topped one half million in the United States, and Nintendo is advising fans to brace themselves for the next wave of Poke-mania. Based on the huge pre-sales for Pokemon Diamond and Pokemon Pearl, Nintendo expects them to be among the top-selling games for all of 2007.
With four days to go until they arrive, more than 533,000 pre-orders have been taken for Pokemon Diamond and Pokemon Pearl. Already these games have more than doubled the pre-sale numbers of Pokemon FireRed and Pokemon LeafGreen, which launched in 2004. Pokemon FireRed and Pokemon LeafGreen went on to sell more than 3.4 million combined in North America.
Pokemon Diamond and Pokemon Pearl have consistently ranked among the top- selling video game products on Amazon.com, and there are still four days until launch.
