The story of BioWare Mythic's "secret" Ultima project keeps bubbling along with an image released that purportedly relates to the game.
If you head over to Ultima Aiera, you'll see a shot from a presentation with what appears to be a (blocky) Brittania map with Paul Barnett (Mythic Creative Director) standing in front. The codename for the project is "Ultima4Ever".
Thanks, Vistaer Dragon.
