In light of MW2, what can Halo Reach do?

[jacks81x]

I think it would be very difficult for a non-true sequel to outsell Halo 3. Halo: ODST came well short. So right there you know that not all Halo 3 diehards are interested in spinoffs. If Bungie makes Halo 4, then I think it will outsell Halo 3.
