This is what comes close to a promise:

 

"Development for X-Plane is completely different from FS9/FSX. In some cases the development for textures was easier X-Plane 9, than in FS9/FSX. However, the process to inject weather has some obstacles to overcome. The developers at Laminar have been great to help us out. We are looking forward to seeing what we can do with X-Plane 10."
