Patrols are very small quests within a game, tiny, tiny things to do to waste time. They are not a large aspect of the game whatsoever. PVP is the easier part of the game to show off, you just need one map and some guns, which is still not a lot of information they've given on it. Saying there is new destinations doesn't really do much for us, we knew there was going to be new destinations. I think the most revealing thing right now is how the Farm works and looks. Still, we know so much more about GT, even months ago, than we do about Destiny, which is just over a month away, but this is going too far off topic.
In short, what we know, and have known about GTS is a lot more than what we know about Destiny at this point.
Other GT's always had large scale media pushes not long before release.
