On top of the hardware figures, Microsoft revealed sales data for leading titles Halo 3 and Mass Effect. Microsoft’s Bungie-developed shooter Halo 3 has sold a staggering 8.1 million copies by the end of the year, while Mass Effect shifted 1.6 million.
Xbox 360 also boasts a record-high software attach rate of 6.9, according to NPD.
Microsoft also addressed problems with its Live service, stating that the problems stemmed from a “massive increase” in new users.
“While the service was not completely offline at any given time, we are disappointed in our performance,” said Xbox Live General Manager Marc Whitten.
