Platform holder Microsoft has predicted that it’s Xbox 360 console will surpass sales of the firm’s debut console outing, the Xbox, by the end of the month.

Edge Online reports that Mindy Mount, CFO of the firm’s Entertainment & devices Division, told the audience at the recent BMO Capital Markets Interactive Entertainment Conference that: “By the end of this month, we expect our global installed base to reach 25 million units, surpassing that of the first Xbox.”

Mount went on to assert that the figure is “only a start”, adding that most consoles experience three quarters of their lifetime sales once they drop below $199 – a price 360 only hit in September.
