Only way I'll cancel my pre-order is if they come out with some sort of limited/collector's edition or someone adds a larger incentive beyond the Avatar armor and Grunt Funeral skull. I loved this game, spent HOURS just replaying single player missions and even more time in multi with my friends... For me, it's part nostalgia, part just that it was a great game, possibly the best in the Halo series. Personally, I see it as far as multi: Halo: CE >= Reach > 3 = ODST > 2, single was probably Reach > 1 > ODST > 3 > 2. I know a lot of people loved the multi in 2, but it just didn't feel right to me, a few of the maps were cool, but the weapons felt wrong...
