Tom said they will pay attention to mod compatibility in the next game, I think that will be a TPF2.0 not a completely new game. The fork may be after the performance patch so I think the principal change is on the parallelism calculation, they will design a new calculation core, since they find the people they were looking for.
The modding problem today, is too strong coupling between datas (partly what CommonAPI is dealing with), which was left from the era of TP, I don't think it will change too much. Since the game is design to first meet UG's spec for the game, not the requirements of modders (which is argumenting everyday)
