On QuakeCon last saturday was held a public demonstration with Rage chief designer Tim Willits and Matt Hooper. Every QuakeCon visitor got the the chance to see 30 minutes of Rage in a demonstration. Of course no fotos or videos were allowed.
Afterwards there was Q&A with the Rage developers.

It seems official content from that demonstration will be released in the near future to public.
