Microsoft might now be wondering why they didn’t undertake a redesign of the Xbox 360 console a lot sooner. The latest data from the NPD Group shows that the June sales figures for the new Xbox 360 slim console beat everything out there, with the exception of the Nintendo DS.

For the month of June, Microsoft sold 451,700 Xbox 360 slim consoles, which beat out the Nintendo Wii at 422,500 and the Sony PlayStation 3 (which only managed sales of 304,800 units). The sales translate into a 35% jump for Microsoft when compared to the numbers in June 2009. Still, software sales remained a bit flat, which has was expected with the number of high profile titles slated for a holiday release.
