We'll probably be seeing these designs coming into production in 5-7 years from now... With the exception of the 3er, X6 and the X5, Every model BMW has entered its new gen design in the past 2 years until now... So I'm guessing the next gen 7er will be based off this design
I'm really looking forward to see where Mercedes-Benz is going with the next gen S-class.... I know its probably going to blow the 7er out of the water...
