Nope. I saw a couple of character designs on the official website, but that's about it. I'm not sure if they've got the funding and the right studio yet.
It looks interesting. I might watch it, if they let the Japanese studio design and storyboard the mecha. After the Robotech: The Sentinels fiasco, I'd prefer it if they go with a more "pure" mecha design. Those designs in that short-lived sequel looked too Western...which doesn't fit the show.
