Man! Nintendo keeps laying the smack down on the others. Check out this article .
July 23, 2007 - "Official NPD data for June is in and, once again, Nintendo's handheld and console dominated the charts. Nintendo DS sold through a whopping 561,000 units for the month and Wii pulled in another 381,000 believers, making the two systems the number-one and number-two best-sellers respectively in June.
Sony's PSP performed surprisingly well, with sales undoubtedly spurred by a recent price drop. The handheld managed 290,000 in sales, which was good enough to nab the third best-selling spot for the month. Meanwhile, PlayStation 2 garnered another 270,000 unit sales, earning it the number-four position.
Xbox 360 sales, at 198,000, were nearly doubled by Wii. Game Boy Advance attracted another 113,000 people and, finally, PlayStation 3 continued to trail behind all competitors with 98,000 in sales -- a number that is up over previous months, but still well behind Wii or Xbox 360.
The top-selling games largely belonged to Nintendo, too. Against IGN's recommendation, Wii owners continued to buy Mario Party 8, which pulled in another 426,000 in sales to become the month's best-selling game. Wii Play nabbed the second slot with 293,000. Pokemon Diamond and Pearl sucked in 288,000 and 214,000 new DS fans respectively and Xbox 360's Forza Motorsport 2 capped out the top five with 197,000 in sales.
Despite low ratings and a lackluster online mode, more than 157,000 people were tricked into buying Pokemon Battle Revolution for Wii. However, in more positive news, Resident Evil 4: Wii Edition managed nearly 150,000 in sales through June after being available for about 10 days."
