Halo4=no bungie. Definately not on my preorder list, but I wasn't that impressed with the control accuracy and responsiveness of reach anyway. over 6000 online matches of halo2 and 2.5k halo3 (including some semi-pro tourneys), but I never found my groove with 3 like I did in 2. Maybe I just burned out on it.
Diablo III is one of the few games my wife will preorder as well, so I am really psyched to get down on it and have some fun!
