Make it sense to use CC4 for Development? If I prepare my Content on CC4 is it compatible in iClone 7? If not, I think I will use CC3 and xchange furthermore., then this is useful for both systems 7+8, right? 

I can not believe that all User switch to iClone8 with this expensive Price tag and therefore want still use iClone 7. 

I think with CC3 and xchange I have more compatibility or ?
