I never liked Halo, ever. I bought Halo 3, hated it, I bought Halo anniversary and hated it by the first half of the mission on campaign. I generally never liked multiplayer on Halo because I was much more used to CoD, so multiplayer was just as bad as the campaign. But this sounds pretty good… a new look to things, the same combat style as the others, some stuff is being brought back, and maybe an interesting campaign. I might play Halo 4 for… maybe 1 or 2 missions on campaign and 1 round on multiplayer then quit. Good thing I'm not the one buying them but my friend is. Sorry major Halo fans but… I have disliked Halo for a long time… that means I actually played Halo, Halo 2, Halo 3, Halo: ODST, and Halo Reach.
P.S. I played Halo Wars as well, it is the only game out of the Halo series that I like.
