I regrettably cannot locate the proper links at this time, but there are reports that Microsoft flight simulator addon creator/publisher "Aerosoft" has begun pursuing the concept of creating a new flight simulator not related to Microsoft's efforts. A browse through their forums should allow you to get a sense of the situation.
Also, a number of former ACES team members have crafted a new simulation company that may be looking toward creating a new sim in the future. Again, I cannot recall what this new organization is called, and cannot seem to readily supply an appropriate link, yet I am sure others here will.
