According to a piece on USA Today, Bungie’s departure from the iconic Master Chief, Halo 3: ODST, has sold around 2.5 million copies since its release two weeks ago. “That’s pretty good for a game that most called an ‘expansion pack,’” as analyst Michael Pachter puts it.

Those 2.5 mil amount up to more than $125 million in sales and add to the franchise’s total sales numbers of 27 million+.

In the same piece, 343 Industries’ (a Microsoft division that handles the Halo franchise) creative director Frank O’Connor also says they have a plan for Halo that goes out “at least six years” and makes it pretty clear that Master Chief is a part of those plans, “I think that [Master Chief's] fate, Cortana’s fate and the identity of that giant, dark planet at the ending (on the game’s hardest skill level) — that’s a spoiler — are probably big mysteries that would be irritating if they were just cliffhangers.” Halo 4: Start A New Fight?
