To your left is a rather fuzzy screenshot of a Forgotten Settlement, leaked by a Russian magazine, taken at a presentation at EALA.
I can tell you that EA aren't happy about this photo being leaked (and a few others taken of boring Powerpoint slides). But it clearly shows the presence of distinct structures for The Forgotten, it even looks like they will have little fires.
We've also learned a little more about the storyline:
Kane meets with GDI high command claiming he can control Tiberium, stabilise the Earth, and give humanity a future. That's just in the prologue we saw in the teaser trailer. Flash forward 15 years, and the world is enjoying the benefits of Kane's Tiberium Control Network. It's a new Golden Age, is what it is, a utopia of gleaming cities, cheap cars and low taxes. But is everything as it seems? Some still question Kane's ultimate motives. Who is he? What does he REALLY want? And what of The Forgotten, that tribe of humans heavily mutated by Tiberium? Stresses with the alliance build, and soon enough fractures appear. NOD and GDI are set against each other once again.
