I remember reading somewhere that a d20 Master Atlas was in the works. I also think I remember reading that it was on indefinite hiatus.
Are there any plans to continue with it? Either as d20, or Pathfinder, or both, for example? The system is still one of the most popular, but I heard that players weren't as happy as they could be with the 4th Edition, so there is still a market for d20.
It could bring more people into Shadow World, and then possibly bring them to Rolemaster.
