there isnt hype right now but in 6 months there will be. the marketing will be as big if not bigger then 3 so there really isnt a reason reach cant outsell halo 3. halo 3 sold 10.5m and the campaign in many peoples eyes was short and sucked so if reach has a good campaign(it should since it has a great story) and the game is north of 10 hours it should and probably will outsell halo 3.
Halo MCC will sell 5+ million copies(including digital)
halo 5 will sell 10 million copies(including digital)
x1 will pass ps4 in USA, and UK.
