I would think they would have announced it if they had shipped 10M. Its too big to not announce... Thats my reasoning anyway.

True but Halo 3 was still selling well early 08, that with Christimas 08, surely its sold more than 1.9 million in the last 19 months?

Honey.... Thats just speculation dearest. Until we see some confirmation we may as well assume its overtracked until proved otherwise as thats the most conservative and leads to less disapointment.

halo 3:odst - 5+ million
halo :reach - 7 million
halo 4 if released this gen - 11million
end of this gen 43 million this gen without halo 4 being released and over 53 million with it.

You forgot "baby" and "sweetums", sugar pie.

45 million.

40 million

Halo 3: ODST is not going to sell 5 million like some people are saying, at least I don't see it. I'm a huge Halo fan but the it is a Halo game without MC, the Halo name is starting to get milked making it less special and the main multiplayer shooter on the 360 is going to be MW2 so I think ODST will reach 3 million tops. I don't know I'm probably just on crack.

Call of Duty 5 is a call of duty made by Treyarch and its not modern warfare. It sold really well too.

One offshoot, Halo Wars, and one spinoff, ODST, in 8 years is not milking.  I think 40 million at least.
