You can read it, but you can't unread it :p
Umm, what?
You're complaining about ODST not having enough new guns when all throughout the Halo series there haven't been many gun changes. And really there are no new guns in ODST. The M7S is Halo 3's SMG with a suppressor, the M6C is Halo: Combat Evolved's Magnum, and the Brute Plasma Rifle is the same as Halo 2's.
And what "more new stuff" could there possibly be? There's now going to be an enhanced visor mode, a new health system, new characters, new maps (Campaign and Multiplayer,) a new game mode called "Firefight," new stories/plots, and new achievements.
I think this game looks awesome. Has a bit of a CoD 4 feel to it even...
