on the new screen shot if u look at the armour of the main guy u will see that the leg has blue on it and also on the arm....does this have to do with live in some way...like they said that u wiil be able to make ur own content for clans and such....

that shot looks like it is for mp....the driver of the warthog is clearly on the red team...maybe this indicates more team colors in halo 2?(red vs. blue vs. gold vs. green?)
