The NPD Group has released the sales data for May and while it was a weak month in both hardware and software, someone's gotta win the gold medal. UFC 2009 Undisputed and the Nintendo DS are kings of very small hills.

Software

• UFC 2009 Undisputed (THQ, Xbox 360, 679.6K)
• Wii Fit (Nintendo, Wii, 352.8K)
• EA Sports Active (EA, Wii, 345.8K)

Software revenue was down 17% and hardware was down 30%. This is the first time that monthly sales for the gaming industry have fell below $1 billion since August 2007, according to the NPD. Still, THQ's no doubt very pleased with how UFC 2009 performed, racking up over a million in sales in half a month. No wonder EA's preparing their own mixed martial arts game.
