just seen a post by one of the GOA guys seems the 3gig patch is mainly voice and language packs which is going to be an optional install and they are not making it available until sometime next week.
so i would think the patch notes i saw and are now scattered across the net are for a pre-live or after patch.
or its a smaller patch before OB i think i heard the yanks say something about a patch of under 1gig.
