The last XBL update someone delved into the hard drive and discovered mass amounts of halo gems. Upcoming playlist names and map names, which have recently been proven to be right. So is there any visible or less than visible things noticed in todays update?
My guess is that they'll be doing some damage control after all the information was leaked this past week. They'll probably also discuss the happenings at PAX. If we're lucky we'll get a sneak peak at another map to come..that'd be something we haven't seen yet.
Hmm, these might be spots that reserve special achievements for the release of Halo 3 mythic. One of those gems is Recon armor, and another Flaming Armor. The rest can't be brought to surface because it needs that Halo 3 mythic disc, or a downloadable content.
The achievements are coming with the Title Update 2, and will be for Legendary maps and Campaign. Source: Bungie.net : Inside Bungie : News
