The Games Workshop site has a not yet finished new Dark Angels page up on their site. While I know this doesn't by itself mean a whole lot, it is just one more piece in a much larger puzzle. Of course with the starter set getting close, the page could be simply be getting an update for that, or for something greater in the near future.
(This is indeed old, and the page has been there awhile). Seems like a waste for the cool pic above.)
