Official modding in AC is vaporware at this point. I am amazed they didn't make that a number one priority. Although I think some modders have held off on rF2 because it WAS a moving target for a while. At this point the physics portion of rF2 has slowed down to the point that modders don't have to fix physics from one build to the next but they still continue to hold off because they think it's still a moving target. Maybe AC is smart to put modders on the back burner for a while and let their fan base pester all the rF2 modders about porting in the meantime.
