Actually one of the Hero System fans Was working on a 6e version (I doubt that you will EVER see anyone work on a version that's been replaced over a decade ago and is 3 versions back).
come over to the Unofficial Hero System boards and talk to the Person working on this about his project (which is think is stalled due to RL issues and HL's steep learning curve for making new content).
