Well, we can't even say that much. All we got was a few seconds of "gameplay", which just showed of some aesthetic, didn't look complete and was not really too useful to draw anything. Even the press wasn't shown too much. Personally, I think people shouldn't be making too many judgements or guesses just yet as it is difficult to draw conclusions. It is interesting to see what people say, many being convinced in fact that they have solid foundations on which to base their "facts" about the game. The video is mainly designed to act as marketing, rather than to show the game. It is Bungie building hype before the game is shown. While I like what Bungie has done in the past, and I am intrigued by the concept, they are creating excitement so the game looks better when they show it. Put simply, the video is an advert; a clever one at that. Regardless, I believe that saying it is/is not faction based is more speculation than set fact. Give it time folks, more will be revealed. (I don't mind excitement and theories, just in case you think I do, I just like to see a little more fact with the facts)
