The manual will generally live on in driver's cars as an alternative - despite the Ferrari decision, which is more reflective of their typical buyer and the F1 heritage. However, the new breed of DCT boxes are very good and much nicer in feel that traditional auto boxes - if the R8 would have been offered with a great DCT and not the crappy single clutch e-gear box, it would surely have outsold the manual hands down given the typical buyer profile. RS5 will not suffer from probably being DSG only - the NA feature will be much more controversial for some though.

In fact, I would not swap back to a manual anymore. I even mostly drive in auto mode, despite having owned and loved four audis in a row all with nice manuals. But I am indeed older and lazyer now...
