September’s US sales numbers released by NPD confirm what everyone, including Microsoft, expected; The price cut and the introduction of the new slimmer model paired with some solid advertising were enough for the PS3 to catapult itself to the top spot in the most systems sold charts while even beating expectations by 15%. Well, that’s almost correct — if you’re not just counting home consoles then the DS still beat it by ~32,000 units, but when it comes to home systems then the PS3 was indeed the biggest seller of the month. Wii was second for a change and the 360 brought up the rear.

Not many surprises for games either, with Halo 3: ODST being the top seller and Madden 10, The Beatles: Rock Band and Guitar Hero 5 all represented.
