I heard Halo 4 was really disappointingly short.

6-8 hours? 

On 'legendary'?  I don't think so.

I finished the game in 8 hour on heroic.  and i had my son playing co-op with me

I'm trying to just do the final mission on legendary -  so much more difficult

D-Joe stats show(ed) that he beat it in 6 hours and 30 minutes on legendary.
