First off, I will say that I do not like Halo. Of course, maybe that's the wrong way to put it. Halo itself is a good game. I dislike that for some reason, Halo became popular for doing something that has been done already (and IMO a lot better) on PCs for many years.

To reply to your topic, I don't think that anything (short of another fluke like Halo 1) can be done to revitalize the new games in the series. I would disagree that adding a new weapon or two, adding space vehicles, or any other individual thing would somehow make it the "best Halo ever".

They (Microsoft/Bungie/whoever makes it) just need to focus on making another solid game with a solid story. They could create a whole new arsenal of weapons. IMO if they simply add 1 weapon, or 1 new vehicle, or 1 new gameplay mechanic, the game will simply feel like an add-on or hack to Halo 1. Ideally, I would like to see a complete reinvention of the game.
