I have a gig after work so I doubt I'll be able to download the update and try it tonight, but I'm very eager to get it and experience the gameplay changes and new maps.

But what's been fun so far is observing some of the forum dialog over at www.bungie.net.  Lots of people are pissed about the update - because they're being banned for using hacked profiles or for some other unallowed modification to their console or XBL account.  Lots of unhappy campers :)  The best thing is that they're pleading with Bungie to be un-banned while the majority of them knew that what they were doing wasn't allowed.  Not a lot of talk about the actual gameplay mods yet.  We shall see very soon...
