Last month, Bungie said a teary farewell to Halo 3. Or so we thought. Instead, it was just a teary... something else, because Bungie have no intentions of leaving the best-selling game behind.
Speaking with IGN at the Game Developers Conference in San Francisco, Bungie's Allen Murray has said "Halo 3 took two and a half years to make, and we're still working on it. We'll probably be working on it for two more years."
Could we be seeing expansions to an expansion (which Halo 3:ODST is)? In this day and age, you just can't count something like that out.
