Today marks the first day in the history of the Xbox console where Microsoft has produced a yearly profit that was positive. Earlier today, the big M’s Xbox Entertainment and Devices Devision posted an unaudited operating income for the quarter ending September 30 of $165 million. Compared to last year, we saw a loss of $142 million. Obviously, all fingers are pointing to the successful Halo 3 release.

In the first day of the game’s US release, Halo 3 generated a whopping $170 million, making it the most popular selling game in video game history. Over the course of the week, Halo 3 sales grew to $300 globally.

Microsoft predicts its total revenues in 2008 will exceed the $58 billion mark, with an operating income of approximately $23 billion.

Now that the Halo 3 honeymoon is over, most 360 gamers are already rallying up for Halo 4, and I can only imagine the crazy profits that game will turn out. The big question on the plate is how Bungie will twist their way out of the awful Halo 3 ending.
