Hopefully 343 releases one for Halo 4, would pre-order it right off the bat!!! Sad thing there wasnt one for halo anniversary 
Wouldn’t you want to see the game first, or play the beta? Then the chances for you being dissatisfied are large. If i knew how reach played i never would have bought it …
Ofcourse I would like to see the game and play the beta before buying but hey, putting $5 down on a game before it comes out just to have the opportunity available when ever you decide to pay-full or decline the pre-order is always a great option. Especcially with Halo, been pre-ordering ever since 0DST.
